![]() ![]() Bullet Typeĭue to the 300 BLK bullet’s larger grain and increased powder, this round’s perceived recoil is stronger than the standard 5.56mm bullet. 300 AAC Blackout in a standard 16″ barrel. Here’s a small table that compares the ballistic performance of 5.56mm NATO and. There is a 1,000 feet per second discrepancy in the two rounds, but that’s expected with such a large grain weight difference. The 5.56mm 55 gr round had 191 ft-lbs at the same yardage. 300 blkout 125 gr round had 993 ft-lbs at 100 yards. 300 blackout really shines is out of a short barrel. The bullet drop becomes much more substantial at range with the. In testing fired from a 16″ barrel, it was shown that 300 blackout had nearly double the ft-lbs on the impact that a 5.56 round had 200 yards and 300 yards. The round can cover more yards and keep velocity better than its heavier counterpart. ![]() What testing has found is that 5.56mm at 500 yards had a high-velocity thanks to the lower weight of the 5.56mm NATO bullet. Some common grain weight you’ll see for 300 blackout is:īoth 5.56 and 300 blackout have been extensively tested. 300 BLK bullet itself, you’ll notice the size difference of the bullets immediately. Some of the most common grain weights for 5.56mm NATO bullets are: There are different grain weights available for both the 5.56mm and the. Specificationįrom the above table, we can see that both cases have the same overall length. 300 Blackout is a necked-down version of. Both bullets have rimless and bottleneck case types, and both are used in rifles and AR pistols. The casings for both the 5.56mm NATO and. To compare the performance of bullets, we will compare both bullets in all sections that are mentioned below: Since 5.56mm bullets were small, high velocity, and provided good thermal ballistics, so much so that it became the standard bullet that is still used by much of NATO forces. Weight count over-packing will put approximate received quantity of (1,005 to 1,015 rounds total). 1,000 rounds within a heavy duty shipper box.Weight count over-packing will put approximate received quantity of (505 to 510 rounds total). 500 rounds within a heavy duty shipper box.If you want piece counted mil-spec ammo, please buy the standard “FedArm” branded ammo instead. Note: Range grade ammunition does not fall under the FedArm satisfaction guarantee & return policy. The inspection labor savings on these rounds is passed onto you! You will receive more rounds than ordered (as per the below) for the chance you find an unsatisfactory round. A very small count of these rounds may deviate slightly from typical mil-spec specifications and may (or may not) contain slightly off-seated projectile or similar minor functional defects, all easily caught when loading your magazine. It differs from “FedArm” brand ammo in that it is not case gauged nor individually inspected by piece. ![]() What is “Range Grade Ammo”? This ammunition is visually inspected in bulk and packaged by weight. Velocity/ Pressure: 2,100 FPS (out of a 16″ rifle barrel at SAAMI pressure specs). Cartridges are loaded with H110, A1680, or similar proper powder to cycle AR-15 actions. Powder is dropped to +/- 0.1 grain accuracy to ensure the highest performance. In the loading process, only the top quality powders and primers are used. It is acid washed and processed to SAAMI specifications and electromagnetically inspected to ensure safe internal tolerances. ![]() Only once-fired military/police brass is used. 308 diameter M62 144 grain pull down military tracer projectiles. This “range grade” ammunition is manufactured in the USA on high end arsenal grade machines and undergoes a loose visual inspection before packing. 300 AAC Blackout (300 BLK) 144 Grain FMJ Tracer / Ball “ Range Grade” Ammunition ![]()
