Suppose you want a practical rifle cartridge "Hollywood" quiet but still powerful enough to excel at home defense, hunting, target practice, and combat. In that case, you want to try the 300 Blackout ammo. The 300 AAC Blackout, also known as 7.62 x 35mm, is an intermediate rifle cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. The M4 carbine is a 5.56×45mm NATO, air-cooled, gas-operated, magazine-fed carbine assault, rifle. The 300 Blackout is more potent than 5.56/.223 (AR-15ammo) when fired out of a barrel that's less than 16 inches long and works reliably with both super- and subsonic ammo. When combined with a suppressor, 300 Blackout ammo can give you one of the most powerful, nearly silent rifles you can have.
How far will a 300 Blackout shoot accurately?
The 300 AAC Blackout Ammo was designed to achieve energies like the 7.62 x 39mm Soviet in an AR-15 while using standard AR magazines at their full capacity. The 7.62 Soviet rifle cartridge taper prevented reliable feeding in AR magazines and created wear on the bolt. From the 14.5 in (370 mm) barrel of the M4 Carbine, the M855 5.56×45mm round has an effective point target range of 500 meters. The bullet has significant drop, drift, and energy loss at that distance. From a 16 in (410 mm) barrel, a 125 gr (8.1 g)300 AAC Blackout Ammo round has a lower velocity and similar bullet drop and drift at shorter distances. However, it has the same amount of energy at 700 meters that the M855 has at 500 meters. The Blackout has an effective range of 460 meters in hit probability. From a 9 in (230 mm) barrel, the 125 gr 300 AAC Blackout Ammo has the same muzzle velocity as the M855 from the M4 and 5 percent more power at 440 meters.
In comparison with 7.62×39mm rounds, 300 AAC Blackout Ammo rounds with varying loads have a better ballistic coefficient and more energy out of similar length barrels. 300 AAC Blackout Ammo rounds like the Barnes Bullets TAC-TX 110 grain "barrier blind" performance, capable of penetration through several inches of different challenging targets. 300 AAC Blackout Ammo allows a user to have one firearm capable of switching between sub-sonic, supersonic V-MAX, or barrier penetrating ammunition, all with just the change of a magazine. It can replace the H&K MP5 for close quarters and bring the fight to longer distances, outperforming the M4 carbine with just a magazine change. The 30 caliber rifle cartridge has an 89.1 percent increase in frontal bullet area over the 5.56×45mm, leaving a larger wound cavity in soft targets. It also penetrates deeper and initially yaws faster .300 AAC Blackout Ammo is effective from barrels as short as 4.5 in (110 mm). Weapons chambered for the round can be as light, compact, and quiet when suppressed as submachine guns like the 9×19mm MP5, 5.7x28mm FN P90, and 4.6×30mm MP7 while having more energy and accuracy at a more extended range.
What is the fastest 300 AAC Blackout Ammo?
Subsonic ammo is lower-powered ammo that only propels bullets to just below the speed of sound. When objects move faster than the speed of sound is around 1,100 fps, they produce what sounds like a small explosion, known as a sonic boom.
The Barnes Bullets VOR-TX 110-grain TSXFB features a 110-grain, polymer-tipped, all-copper Triple-Shock bullet that achieves 2,400 fps from a 16-inch barrel, producing 1,407 foot-pounds of energy.
To eliminate this sonic boom, you need to use bullets that travel below the speed of sound or less than 1,100 fps. Reducing this speed would also reduce the bullet's energy.
What is the best grain weight for 300 AAC Blackout Ammo?
Planning to go deer or hog hunting, or if you're looking for rifle ammunition for self-defense, you can use 300 aac Blackout 110. Look for a bullet weight between 125-135 grains and a bullet type of SST, OTM (open tip match), or polymer tip. At 100 yards or closer, the 300 AAC Blackout cartridge will kill a deer or an intruder.
