Barrel Length Studies in 5.56mm NATO Weapons. As each set of measurements is recorded, the barrel was shortened (and re-crowned) an inch at a time and the pressure sensor moved to the resulting farthest location. In this photo, the barrel has been shortened to eight inches. There has been a cultural shift from the 20-inch barrel length in the. This allows it to keep a supersonic muzzle velocity at 1,000 yards. At that distance, it retains 400 ft lbs of energy. Compare that to a 5.56 Ball M193 round's 55 grain bullet, which delivers a 3,265 fps muzzle velocity, 1,302 ft lbs muzzle energy, and 0.272 ballistic coefficient. At 1,000 yards its 947 fps velocity falls beneath the speed of. Data Based Conclusions: Self-Defense: Like the Army says, the 5.56 is effective for self-defense well beyond 500 yards. Whether you can even consider a target to be a threat at that range, however, is another matter altogether. Hunting: The 5.56 consistently fails to deliver 1,000 ft lbs of energy beyond 100 yards 2,254. Oct 29, 2020. #8/8. I've updated my chart to include M193 and 62gr and 70gr TSX loads. Considering the TSX is pretty nicely barrier blind, it seems ideal or people who only ever intend to engage within the POA/POI range of 5.56 with a 50 yard zero (225/250 yards and in). For the TSX muzzle velocities, the 10.5, 14.5, 16, and. 5.56 NATO 10.5 Starting Load Maximum Load Case: Twist Rate: 1:7 Charge Velocity Charge Velocity Powder (grains) (fps) (grains) (fps) RL 10X (Alliant) 21.2 2623 23.2 2756 A-2460 (Accurate) 23.4 2575 25.4 2739 H335 (Hodgdon) 23.0 2475 25.0 2662 TAC (Ramshot) 25.2 2601 27.2 2794 H4895 (Hodgdon) 24.2 2538 26.2 2756 IMR 4895 (IMR) 24.6 2528 26.6 272
This is a .223 ballistics chart (external) generated using our ballistic trajectory calculator. Based off a standard 55gr bullet leaving the barrel at 3,215fps and follows the bullet trajectry all the way to 1000 yards in steps of 50 yard increments. The charting shows the range, drop (based off a 1.5 scope mount), current velocity, energy. The 5.56×45mm NATO inspired an international tendency towards relatively small sized, light weight, high velocity military service cartridges that produce relatively low bolt thrust and free recoil impulse, favoring light weight arms design and automatic fire accuracy 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. 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 5.56 NATO 16.5 Starting Load Maximum Load Case: Twist Rate: 1:7 Charge Velocity Charge Velocity Powder (grains) (fps) (grains) (fps) RL 10X (Alliant) 21.2 2864 23.2 3022 A-2460 (Accurate) 23.4 2806 25.4 3010 H335 (Hodgdon) 23.0 2649 25.0 2900 TAC (Ramshot) 25.2 2840 27.2 3075 H4895 (Hodgdon) 24.2 2851 26.2 3028 IMR 4895 (IMR) 24.6 2807 26.6 302 Welcome to Ballistics By The Inch, or 'BBTI' as people have taken to calling it. Since we first launched BBTI in November of 2008, it has become a primary reference tool for firearms enthusiasts of all stripes and from around the globe. Our initial research data covered the relationship between barrel length and velocity for some 13 common.
While the original Mk262/77gr SMK's BC is very close to that of the 147-150 gr 7.62x51mm's ballistic performance, the new polymer tip bullet of Black Hills 77 gr TMK gives it the long range performance near the heavier 168 gr .308 caliber bullet. Black Hills' three 77 grain (5 g) 5.56mm ammo. The Mk262 military load on the left However, given common differences in loads and throats, it's a good idea not to use 5.56mm ammo in a firearm with a dedicated .223 chamber. In 1979, SAAMI cautioned that 5.56 chambers differ from those in .223 sporting rifles, and that use of 5.56 ammo in .223 rifles could jack pressures to unsafe levels Using 500 meters as a benchmark, a NATO standard 5.56x45mm M855 projectile fired at 2,900 FPS will have 100 inches of drop, 41 inches of drift, and 291 ft.-lbs. of energy at that distance. In contrast, a .300 Blackout 125 grain projectile at 2,220 FPS has: 100 inches drop at 440 meters. 41 inches drift at 484 meters
The relatively fast velocity of M193 ammunition at 3,250 fps makes it arrive at its target marginally quicker than its 5.56 counterparts. Kinetic energy is solved for using this equation: K=1/2mv2. By plugging in mass at 3.63 g and velocity at 3,250 fps (this formula utilizes meters, so 991 mps), we can determine that the total kinetic energy. So using the faster powders and 77's you will not be able to get the velocity of the slower powders such as Accurate 2520. We think this powder is the best choice for reloading 5.56 Ammo. 5.56 Summary Charts. Powder average MOA, Std Deviations, Velocity for load area, different bullets, huge database. According to the ballistics charts, the range for muzzle velocity is fairly vast. Depending on the bullet weight and powder load, anywhere from 2,800fps (853mps) to 3,300 fps (1,006mps). Lighter bullets (40 to 55 grains) with heavier powder loads.
With the popularity of the AR platform and the .223/5.56 round I thought it would be a good idea to review the trajectory of the round and common sighting ranges. Being a high velocity round the trajectory is relatively flat within a few hundred yards - past 400 the drop-off is significant. There are several philosophies on sighting in the AR and what range in best. Here are a few examples. The formula for determining a bullet's spin rate when it leaves the muzzle is: RPM = velocity times 12 divided by twist rate, times 60. As an example, let's say a rifle barrel had a twist rate of 1:9 and the bullet exited the muzzle at 3000 fps. 12/9=1.33, 1.33X3000=4000, 4000X60= 240,000 RPM. In this example, when the velocity of the bullet. Dr. Vincent DiMaio, a renowned expert in wound ballistics, says that the 5.56 x 45 mm cartridge fired from the M-16 rifle series (including the AR-15) is the most famous of the available high-velocity cartridges.. This round is a 55 (or 62) grain bullet that leaves the rifle muzzle at 3250 feet per second (fps) - roughly three times the speed of modern handgun rounds
(this thread probably doesn't belong in the terminal ballistic forum) AR-15 Zeros and Trajectories The 100 yard zero with a .223/5.56mm AR-15 carbine is a unique trajectory in that the bullet just kisses the line of sight at 100 yards and rides along it for approximately 10 yards before dropping back down below the line of sight However, most 5.56 ammo is tested through 20-inch barrels rather than 24-inch barrels, so the velocity increase often isn't immediately obvious on factory ballistic charts. Chopping the barrel to the far more common 16-inch length reduces velocity in wildly varying degrees, depending on specific ammunition and barrel
The 5.56 was designed for the M16, which features a 20 inch barrel, and the bullet uses all of this length to get up to a velocity of 3,000 feet per second. So as the barrel length is decreased, the bullet exit velocity also decreases, since the gases don't have enough time to get the bullet up to speed before the bullet is expelled The 4.82-inch barrel of the FN FiveseveN and the 4.94-inch barrel of the Ruger-57 are going to produce less velocity and less energy than the P90. From the P90, a 5.7mm projectile will achieve velocities in excess of 2,000 fps and muzzle energy in excess of 340 ft-lbs, and top out close to 3,000 fps and 400 ft-lbs A M193 (the military standard 55gr 5.56 cartridge) generates a velocity around 2750 fps in a 10.5 barrel AR-15. This isn't much higher than the fragmentation velocity. Since the bullet will be losing speed every moment after it leaves the barrel, we can figure out it's going to drop below the magic velocity threshold around 20 meters 1162. 1114. 1047.

In addition to extensive discussion about ballistics to be found at many gun forums, here are some other great resources pertaining to ballistics testing you should check out
The 5.56×45, with its much lighter bullet weights and similar powder loads, gives you a much faster bullet from the muzzle out to 500 yards. These rounds have an average muzzle velocity of 3,038ft.sec and end at the 500-yard mark with an average of 1,645ft.sec. All of the 5.56×45 rounds remain at supersonic speeds throughout the 500-yard range Its muzzle velocity is a little slower - except when compared to a match 5.56 round with a heavyweight 77 grain bullet, which offers a muzzle velocity in the ballpark of 2,750 fps - yet the 6.5 compensates for this with a significantly heavier and more ballistically efficient bullet Velocity offers Free Shipping on all orders over $100 no matter how large the order.

Therefore, 5.56mm NATO ammo isn't safe for use in a rifle chambered for .223 Remington, but .223 is OK in 5.56. Thus, powder charge is the main difference between 5.56 vs .223 cartridges. Wait Joined Oct 17, 2008. ·. 2,744 Posts. #2 · Oct 3, 2010. The only way to find out is to chrono that round in that barrel but the problem you will find is that there are different barrel which in turn will give different results. You can make a 5.56 hit it's velocity out of a 7.5in barrel if you handload. 1 Well, it depends. Though the cartridges of both 5.56 and .223 are identical in their external dimensions, 5.56 is frequently loaded to higher pressures. Not all AR-15s are rated to handle the higher pressures of 5.56, as some are solely designed to use .223 Remington. The rules are: Firearms chambered in 5.56 can safely shoot both 5.56 and .223

Between 6.5 Grendel vs 5.56 NATO ammunition are compatible with the AR-15, but shooters want to know which works better for the AR-15. So, the team decided to test both in the shooting range. We noticed that during the test, the 5.56 shoots faster compared to the 6.5 Grendel because it has less recoil
.308 Win vs 5.56 Nato Cost. Now, compare the 308 vs 556 ammo cost. Usually, bigger projectiles, which are 308 ammo, cost more money. There are a few reasons for this. To keep it simple, they need more material for production. Because of this, the 5.56 Nato ammo is cheaper by about $6 to $7 per box of 20 rounds Despite losing 28% of its velocity, the 5.56 is still moving 34% faster than the supersonic 300 Blackout at 200 yards, making it the better choice at that range.

Conclusion To satisfy the curiosity of the authors about the effects of barrel length in the 5.56×45 NATO weapons, an experiment was crafted to measure actual bore pressure in the barrel at the moment of projectile exit, velocity, and sound pressure level with a barrel length varying between 24 and 5 inches This length of barrel is known for its overall effectiveness. It should be kept in mind that legally, the shortest barrel you can get for an AR is 16″. You might be able to get away with a 14.5″ barrel if you pin a muzzle device on it to make the barrel 16″. Moving forward, the 16″ is perfect for any use, extremely reliable and most.
Most AR-15s chambered in 5.56 or .223 use a 1:7 or 1:8 twist rate. 300 Blackout favors 1:8, while the LR-308 works well with 1:10. Barrel length doesn't equal accuracy, velocity and twist rate does. Only buy a barrel that's long enough to maximize velocity before diminishing returns 5.56 cases. Velocities of the Barnes bullets, shot from a Ruger Gunsite Scout Rifle's 16.1-inch barrel, varied only 33 fps between the five makes of cases loaded with 25.0 grains of X-Terminator. Those differences in velocity were nearly the same as the 30 fps extreme velocity spreads re-corded for the different cases. For a .308 Winchester load To measure velocity, a Magnetospeed V3 chronograph was used attached to the barrels of the 16.1″ and 20″ uppers, and the rail of the 14.5″ upper. In addition, three 10 shot groups were shot for each round through my Criterion 14.5″ chrome-lined 1:8 twist hybrid contour midlength barrel in .223 Wylde, to determine accuracy
