Trajectory for Custom .308 125 TGK 4625A–10 at 2115 Feet per Second. Roughly equal to a 30-30 or 7.62x39. 300 AAC Blackout ammo, SAAMI short name 300 BLK, also known as 7.62×35mm is a rifle cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. And really, I’m not sure the difference matters to any whitetail out there. But for 0-200 yards it's a pretty good round. There is, however, one element of bullet wounding that is universally accepted. This gives it the edge with short barrels and suppressors, which makes … On the subsonic side, the first dot is good to 50 yards and the second dot is good out to 150 yards. For instance, the bullet drop from 100 to 200 meters is 1.5”, notably less than the .300 AAC Blackout. If you are talking about hit probability, the .300 Blackout usually has an effective range of … According to some 300 Blackout owners, pistol-length is considered to be a popular choice. The dots correspond with bullet drop for both subsonic and supersonic projectiles. 1833. Where are you getting these numbers from? 1377. From what I understand, they were provided for your in flight reading pleasure while aboard the Concorde, which has been removed from service. more weight by itself, yes it takes a lower twist rate. If, however, you are building your rifle around a specific bullet weight and load, then twist rate is a valid consideration for optimizing that load. Need 200 yards of knockdown power? yep that’s where 300BLK is at its best. The lower velocity also means it's more of a challenge to find a good expanding hunting load at around 2,000-2,200 fps for a 125g bullet. 820. Those are two VASTLY different 5.56 loads. Bullet Energy Calculator; Firearms; Ammunition; Accessories; TV Shows. According to some 300 Blackout owners, pistol-length is considered to be a popular choice. I was starting to think it was just another thing Washington banned. Please let me know how it can be improved upon. The .300 blackout out of an equal length barrel is far superior inside 150 yards as the bullet drop is negligible and the round is larger (more material to expand), less gasey, less muzzle climb (added felt recoil) quieter suppressed or not, MUCH more powerful, and can reliably cycle subs and supers out of a much shorter barrel with power equal to .556 in longer barrels. diversmith. I'm not sure what the charts called, ballistic drop chart perhaps, but I'm looking for the ballistic drop chart for Sig Sauer .300 Blackout 220 gr Sierra Match King Elite Match Grade subsonic ammo. Wind Direction is: 3.0 o’clock and a Wind Velocity of: 10.0 Miles per hour. Let’s look at how well AAC accomplished their goal by analyzing its ballistics. Not sure how you think 300BLK isn’t going to overpenetrate. Likely higher $$$$ in both the rifle, and the ammo. Posted: 10/27/2020 12:18:59 AM EST I have a new 300 blackout upper I'm thinking of putting my thermal scope on and using for coyote hunting close to town. Because when a rifle bullet slows down it becomes much less effective at expanding (think driving your car into a brick wall at 20 mph). but, for the same caliber, more weight means longer projectile, and that requires a tighter twist rate. However, the .300blk is a huge step up in ballistic performance in the ar15 for two main reasons; the diameter of the bullet is 50% larger to begin with and it has a substantial increase in bullet mass. 1377. The same holds true for bullet drop: Subsonic 300 Blackout outperforms 5.56 NATO by offering the same bullet drop from muzzle to 700 yards while affording over twice the kinetic energy. And it’s probably the most important thing to remember when looking at this cartridge and why it exists. 50 Yards. Pretty much everyone else knew what he was talking about. 300 BLK when the barrel is less than 12″ or suppressed. 200 Yards. Accuracy has been 1 MOA or less with it. I’m skeptical even with 5.56 pressures, you’re going to see 77gr getting 2573fps out of a 9” barrel. Nope… I’m waiting until next week when the Acme 6.33mm Roadrunner Laser Emulator cartridge is released– surely that will put an end to all of these silly discussions !! Come on, Dan. Out of a 16” barrel I’m getting about 2580fps for 75gr Hornady. and 120 Gr. Furthermore, you could throw in a supersonic magazine that overwhelming surpasses the pistol calibers at range. While the Russians went with the 9mm Luger bullet, American war fighters turned up the 5.56 NATO case and then necking […] (Bacon and eggs) You are BOTH a special kind of stupid, AND just like to say things about which you have no clue. Terminal Ballistics is everything that happens between the bullet hitting its target and it finally coming to rest. The author here said that “the longer and heavier the bullet is, the tighter the twist rate needed to stabilize it.” My physics is weak but playing around with the Miller twist rate calculator it looks like bullets require less twist to stabilize as their mass increases, no? Facebook; Instagram; Youtube; About Us. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. The 5.56 had at least 500 FPS on the 300 Blackout for velocity, slightly decreased muzzle energy, a little less than half the bullet drop, and less wind drift. Big yawn, until someone put a suppressor on their SBR loaded with subsonic ammunition. similarity to 7.62×39 was not the original intention, just a bonus. The velocities were extremely close for all except the pistol cartridges which finished roughly 200 fps slower than the rifle cartridges. The M1A and Mini-14 are more robust than an AR-15?… Hahahahahahahahahahahahahhahahahahahahahaha *breath* Hahahahahahahahahahahahahahahahaha. 250 Yards. For range use, I’m going to say no. as for M855A1 vs M193, no M855A1 is not better unless you are shooting at armored targets hundreds of yards away. Nonetheless, it will have the same amount of force at 700 meters that the M855 has at 500m! I confess that I was compelled to reassess my prejudices against the .300 blackout last Fourth of July. 1071 . It will a produce a line graph showing the bullet drop and flight path of the bullet. We make a Pistol/SBR load which is optimized for barrels between 7-11” and a Carbine load which is optimized for 16” barrels. Ballistics is a broad term that actually covers three subsections: Internal ballistics, external ballistics. now try that in a 16″ barrel. That’s pretty much all wrong. The two most important variables are the Initial Velocity and the Ballistic Coefficient. Let’s look at all three.”. The author is as literally incompetent as the infamous Hoober. No worries, the 300Blackout achieves small/medium game kills relatively easily [with either subsonic or supersonic ammo]. .223 Chinese hackers have infiltrated the internet and have been successful in completely disabling sarc detectors. A rifle bullet going slow (under ~1800 fps is slow) is going to be significantly less effective. Velocity Boundaries (Feet per Second) of: 2700 1400 1400 1400. 50 Yards. It also depends on your state laws. Its purpose is to achieve ballistics similar to the 7.62×39mm Soviet cartridge in an AR-15 platform while using standard AR-15 magazines at their normal capacity. The motion of the gas piston presumably deflects the rifle from point of aim. I searched online but couldn't find it. The M&P15 in .300 Blackout gets a 125-grain bullet up to more than 2,300 fps. 1217. at that point fragmentation is not its purpose. “Ballistics is a broad term that actually covers three subsections: Internal ballistics, external ballistics. I did this for two reasons. A good DM/battle rifle. We demonstrate what happens if you accidently chamber a 300 blackout round in a 5.56 rifle. Bullet drop and velocity of 5.56 vs .300 AAC Blackout The 300 BLK also has a much easier time handling both subsonic and supersonic ammo, especially without any additional ammunition. 5.56 is the best option for reaching out and touching something. That being said, at close ranges with subsonic loadings, the .30 caliber bullet may be the best choice. Member Joined Apr 2002; Posts 4583; EE 100% (327) NV, USA. If you are talking about hit probability, the .300 Blackout usually has an effective range of around 460m. However; a Ruger Mini-14 in stainless steel would be a close second pick. checked it out. 300 AAC Blackout ammo, SAAMI short name 300 BLK, also known as 7.62×35mm is a rifle cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. variety: This misses the reason 300 BO was developed in the first place, it is designed to fit in a roughly MP5SD sized platform but have longer range than 9MM. The .45 had the most energy at the muzzle but quickly fell behind as the distance increased. Your information will never be shared and you can unsubscribe with one click at anytime. I wrote it off as another wildcard cartridge but my next build, if I ever get the money for it, will be a 300AAC blackout. I switch uppers without a problem with my buffer…but the uppers are set for optimal gassing, it seems to me. The .300 AAC Blackout ... a 125 gr (8.1 g) 300 BLK round has a lower velocity and similar bullet drop and drift at shorter distances. And when I say “slightly” decreased energy, I’m talking within 50 ft/lbs at any distance, with the 5.56 actually outperforming 300 BLK at some. This is why the troops in Vietnam referred to the M-16 as the Mattel 16. In order to keep this article at a reasonable length, we will be looking at the ballistics through a set of pre-determined filters. I’ll keep what I have…young Kyle sure showed the efficiency of 556(maybe 223)in Kenosha. AAC offers 1:7 in all three of their barrel lengths. 622. If you do not have a Shooting Chronograph, I strongly suggest you purchase one. However; if you have a fettish for a SBR, the .556 looses this advantage. a reminder, though, you can’t just pop in a magazine and switch from subsomic to supersonic like that, or take on or off a suppressor. There are a huge number of factors and variables that can’t be properly accounted for, and certainly not agreed upon. On the other end of the spectrum are loads that send their bullet traveling faster than the sound barrier. M193 is better for everything closer. However, due to the increased weight of the projectile, it will provide more kinetic energy on target at 500 meters and will provide the same kinetic energy as the 5.56 M855 cartridge out to 700 meters. The muzzle velocities are an estimate because most published velocities use longer barrels like 20 or 24 inches. Uhh… I think you might be confusing M855 with M855A1. Mk 262 Mod 0 The email address you entered is not valid. When a bullet strikes a body, it will put a hole in that body slightly bigger than the diameter of the bullet. The Discreet Ballistics 300 Blackout 190gr Subsonic Target Load is intended for use in semi-automatic and bolt action firearms chambered in 300 AAC Blackout. I don't see much worth in it unless he is going that path. So, using BCs generated from supersonic loads would give us less accurate trajectories than if we used BCs generated from subsonic loads. Really designed as a round for a silenced weapon. Posted: 10/27/2020 12:18:59 AM EST I have a new 300 blackout upper I'm thinking of putting my thermal scope on and using for coyote hunting close to town. Oh and being suppressed was also a top design requirement so, subsonic loads. And if that number is wrong, your suppositions on energy are a lot further off as well. Alternatively, replace the anti-material rifle with the DM rifle and have a SBR if you are in close and dirty. The 7.62×39 ammunition is basically identical to the 300 BLK ammunition. I'm looking for some numbers on what the drops might be … This is expected, since the bullet weights are nearly half that of the others. Indeed. Barnes 300 Blackout TAC-TX bullets fired from 9" and 16" barrels into 10% bare ordnance ballistics gelatin. The 5.56 is the only exception. diversmith. 5.56: 60 cents a round M855A1 If you’re looking for a gas system that will give you the ability to shoot rounds that will hit targets effectively from about 200 yards out, this is the gas system to go with. At any rate, there are four relevant ballistic phases, if you include transitional ballistics. This just in…. 100 Yards. point and shoot. As I tell my Wife guns are like golf clubs, you need a big set to do different things and different jobs at different ranges! I want this to be the best ballistic trajectory calculator out there. It may be statutory rape in most states, unless….you are only 18 in Virginia, or only 26 in the New(som) California, and so on. I think 300BLK is great. Maybe the most significant application of this is barrel twist rate. 961. 100 Yards. 820. People keep talking about using a 9″ barrel suppressed, but 300 BLK suppressed is much quieter from a longer barrel, at least 14.5″, even better with a 16 or 18″ barrel. From a 16’ (410mm) barrel, a 125gr (8.1g) .300 Blackout round will have a lower velocity and similar bullet drop and drift at shorter distances. M855 By comparing to 5.56 NATO again, we can find the max effective range of 300 Blackout based on ballistic data. This is what most people refer to when they talk ballistics. From the military’s perspective, that’s ideal. Do I get to claim versatility again? Hornady makes great ammuntion, especially for hunting, like the 135gr FTX That’s quite a bit of variety…. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bullet weight, Love the BO but only to ranges of a hundred fifty yards or less. The following ammunition cartridge ballistics information and chart can be used to approximately compare .30-30 Winchester vs .300 AAC Blackout ammo rounds. The 300 BLK round is a 5.56 replacement, with 7.62×39 capabilities with minimal alterations required for the weapon system. The performance difference between the rounds is insane. It is early for me so I could be confused I suppose. yes, you get to claim versatility. M855A1 is definitely better. So, while there is a stark contrast in bullet size between the two cartridges in the photo, that’s not the case when the .300 Blackout is using a lighter 125gr bullet. By the math, .300 Blackout will experience greater drop due to being fired at a slower velocity, thereby increasing the amount of holdover required to hit a target at the same distance. The implied sexual arrangement is considered statutory rape in most States. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Hunting with a .300 blackout is a bit of touch and go and you have to follow many of the same rules you’d use for similar class rifle rounds such as the 7.62×39 and .30-30. External ballistics is everything that happens to the bullet between the muzzle and the target. We demonstrate what happens if you accidently chamber a 300 blackout round in a 5.56 rifle. The 208, 210, and 220’s are for home/close defense. Give me something as quiet as a MP5SD than can compete with x39 when the bad guys see us. By comparison, 300 Blackout only requires a barrel change. The army was compelled to publish a propaganda comic book on how to clean and maintain the finicky rifle by referring to it as “the sweet sixteen.”. The 5.56 had at least 500 FPS on the 300 Blackout for velocity, slightly decreased muzzle energy, a little less than half the bullet drop, and less wind drift. I understand that bigger bullets generally make larger diameter wound channels. If the bullet hits bone, the 5.56 is generally equal to the .300 blackout. The M80A1 photo isn’t as clean, but I think it still properly illustrates the difference in wound size between the two rounds. Across the board, the 300 BLK rounds were only minimally better if not worse than military grade 5.56. This can be useful in comparing cartridges or loads. But, after looking at the numbers, AAC definitely succeeded in seamlessly putting 7.62×39 performance into a standard AR-15 platform. Or that once in a life time 10 point buck. YouTube is full of ballistic gel test videos showing M855A1 and M80A1 performance, including this video which shows the M80A1s effectiveness in the 300 BLK platform. 2094. Fact is, I want a round that can do 90% of what I need it to do. Advertisement & Review Requests; Our Friends; Contact Us; Donate ; Donate; 300 AAC Blackout Ballistics Chart--> Get your 300 AAC Blackout Ammo from our friends at AmmunitionToGo.com <--American Eagle Ammunition Ballistics: Round Type Weight … Theoretically, the 300 Blackout has the performance to make it a threat at 500 yards, though it’s doubtful most will take it this distance. This gap does widen as the bullets move out to the 300-yard range with the bullet drop of the .300 BLK rounds dropping 15-20″ more than the .308 Win rounds. 300 AAC Blackout. This round has been thoroughly tested to function in both pistol and carbine length gas systems. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. The drop rates were also very similar, with the pistols again underperforming. to penetrate common ballistic vests. When the noise rates are a bit too noisy though, you should also use ear protection. The bullets are specifically designed to expand at subsonic velocities (750 fps and higher). The 110 Gr. Likely a Safe Queen. You can find an email form and contact information here. Despite using estimated muzzle velocities, I’m not really seeing any hint of the 300 BLK rounds being better by any significant margin, or at all. I read that 6 times before i figured out what was going on. You well know, though, that the drive behind the creation of the .300 BLK was to provide a round that could be fired in a suppressed M4-rifle with only a barrel change, so with a 220 grain bullet. To the question, how many guns do you need? The Radical Firearms 300 AAC Blackout Upper Assembly is a flat top, law-enforcement grade, drop in receiver, ready to be mounted to any Mil-Spec AR-15 lower receiver! However, you need to have a correct choice of buffer to make them all work. Bullet Energy Calculator; Firearms; Ammunition; Accessories; TV Shows. What is a supersonic magazine? yep I was thinking of M855 green tip. I tried catching a bullet in a tub of water that was 24″ long set at 50 yards. The subsonic results were pretty similar to each other. We make a Pistol/SBR load which is optimized for barrels between 7-11” and a Carbine load which is optimized for 16” barrels. If you’re using lighter bullets a slower twist rate can give better performance. I want that rifle I be willing to take out in the rain, snow, sleet, and not have to worry about squeeze trigger go click. The cartridges are loaded with 188 gr expanding machined copper projectiles called Selous. So, while there is a stark contrast in bullet size between the two cartridges in the photo, that’s not the case when the .300 Blackout is using a lighter 125gr bullet. In general, the longer and heavier the bullet is, the tighter the twist rate needed to stabilize it. . I would prefer it over 5.56. the only thing that keeps me from swapping calibers is the overwhelmingly plentiful supply and variety of 5.56. This is important because the Ballistic Coefficient of a bullet changes depending on the velocity. at least to 400 yards. Velocity is not super high, which means a lot of bullet drop at longer ranges. no I’m not a special kind of stupid, you’re just a special kind of asshole. Despite what POTENTIAL energy the bullet has, it only matters what it can transfer. The accompanying images show several different common loadings of 5.56 NATO, 7.62×39, and 300 BLK. Some may include a shotgun, but I consider that to be a piece of utility equipment. At an Elevation Angle of: 0 degrees . Tumbling and fragmentation increase the size of the wound, but the 300 BLK will always have a slight size advantage over the 5.56. The disparity in the BCs makes me think that either Engel is underestimating their BC or Hornady is overestimating theirs. Velocity (FPS) Energy (ft/lb) 2375. 250 Yards. The winding effects from the little .556 is almost magical if and when when it tumbles. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bullet … In the end it depends on what scenarios you expect to encounter. 300 BLK 110 Gr. I hunt, in Free America, all the time with mine as does my family and none of us jumped ship to .300. However; penetration depth is important. 1071 . Yet another reason why 5/3’s of all Americans don’t understand fractions. Also, wrt “variety” of 5.56 rounds – the 300 Blackout can use projectiles from ~100gr to 240gr. Bolt-hold open on last round on all four modes. Why is this important? Because the 300 BLK is the next logical progression for the AR 15 style rifles, inevitably you will want optics--and not just any scope but the best scope for 300 Blackout rifles and pistols. Andrew at The chopping block/ar15.com This means that after 150 yards, supersonic 300 BLK loses significant effectiveness, and subsonic is going so slow as to not expand at all (minus a couple specialty loads, which still have poor expansion compared to supersonic and are only good within ~80 yards). Of course the CZ Scorpion with a short barrel and suppressor was equally impressive. The .300 blackout out of an equal length barrel is far superior inside 150 yards as the bullet drop is negligible and the round is larger (more material to expand), less gasey, less muzzle climb (added felt recoil) quieter suppressed or not, MUCH more powerful, and can reliably cycle subs and supers out of a much shorter barrel with power equal to .556 in longer barrels. From hunting varmints, to deer or even bear, to target shooting at longer ranges (500-1000yrds), to anti-material, to two legged varmints. This gives it the edge with short barrels and suppressors, which makes sense as it was partly designed for these things. The primary weapon system will be an M4/AR-15 platform with an AAC upper using a 9-inch barrel and pistol length gas system. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Yeah. Been there. Additionally, since the .300 Blackout is designed for use with a standard M-16/M-4 bolt, it has the same size rim diameter (.378″) as the .223 Remington/5.56 NATO. But for 0-200 yards it's a pretty good round. be more inclined to use it than the 5.56, but still too limited. Is it better than 5.56? Especially in an SBR PDW-type role. Other than that, I’m leaning towards 300 Blackout as the better option. and 120 Gr. Barnes 300 Blackout TAC-TX bullets fired from 9" and 16" barrels into 10% bare ordnance ballistics gelatin. Don’t get shitty with someone else having a typo. Did I read correctly that velocities were…derived from a load table and subtracting 25fps per inch of barrel loss? The dots correspond with bullet drop for both subsonic and supersonic projectiles. First, Hornady is a reputable manufacturer. This tells me that AAC, the company that has fine-tuned their M4/AR-15 platforms to work with high velocity supersonic ammo and low velocity subsonic ammo, deems this the most versatile twist rate. Thank you. In relation to hit probability, the .300 Blackout would have an average effective range of 460 meters. This may actually be recommended if you plan to use your .300 Blackout in extended shooting sessions. I’ll probably go through the trouble to get it suppressed. Let’s look at all three. Please proceed with caution while posting replies. An important fact to remember, you need velocity (perhaps greater than 2,000 f.p.s.) 150 Yards. Typographical error. TAC-TX bullets perform consistently on small- and medium-sized game to 300 yards for DRT performance. By this logic alone, 300 Blackout rounds are better than 5.56. .300 blk: $1 a round Don’t get me wrong, both will kill. It passed completely through with plenty of energy left over. The 5.56 had at least 500 FPS on the 300 Blackout for velocity, slightly decreased muzzle energy, a little less than half the bullet drop, and less wind drift. You should see the twist rate on the 16″ guns in Iowa class battleships. Facebook; Instagram; Youtube; About Us. Velocity is not super high, which means a lot of bullet drop at longer ranges. it is really good in short barrels, no doubt about that. Roughly equal to a 30-30 or 7.62x39. Discreet Ballistics has introduced new subsonic .300 AAC Blackout loads for hunting and defensive use. Give me a .308WIN, 30-06, or half a dozen other common caliber rounds in a good rifle any day. Additionally, since the .300 Blackout is designed for use with a standard M-16/M-4 bolt, it has the same size rim diameter (.378″) as the .223 Remington/5.56 NATO. The only alleged advantage of direct blowback is a potential increase in accuracy. 1596. While I now am more favorably impressed by the .300 Blackout, it style would not be my first pick for my only gun of the SHTF. Free Klye! Everyone brought some guns for some informal target shooting. That is a AAC 300 Blackout Handi Rifle and no bullet drop calculated as he emerged from the woods about sixty yards away. “ Furthermore, you could throw in a supersonic magazine that overwhelming surpasses the pistol calibers at range.”. The M80A1 photo isn’t as clean, but I think it still properly illustrates the difference in wound size between the two rounds. It will a produce a line graph showing the bullet drop and flight path of the bullet. Compare Products. Each cartridge is subject to the same degree of error, since I will be doing the same math for each. The 208 gr Hornady bullet is an odd exception. all have different purposes. Who Are We? If you refer to the supersonics for HD, sure they will overpenetrate. so M855A1 is better for cold-war style military engagements of armored targets at hundreds of yards. I don’t think 300 BLK replaces 5.56 NATO. It can make use of the multitude of bullets (hunting and otherwise) used for .308.
