300 Blackout Ammo for Sale!

300 Blackout, 300 BLK, 300 BO. All of these names talk about one of the newest, large commercial success stories on the market. That being said, the origins of 300 Blackout ammo are nothing new. Often thought of as the inspiration for .300 Blackout, the 300 Whisper was developed by JD Jones back in the early 1990s, using the 221 Fireball as a parent case. For a bunch of a reasons that we won’t get into here, the 300 Whisper never really achieved wide commercial success. Whereas 300 AAC Blackout, a joint project between Remington and AAC, took a slightly different approach by using a shortened 300 Blackout/5.56 NATO case. This allowed for an easy modification to existing AR pattern rifles by only requiring a barrel change. The ability to use the same magazines, bolts, bolt carriers and other major components as standard 223 Rem rifles made the 300 Blackout a breakout success.

The primary design feature and goal of 300 Blackout is the ability to easily switch between subsonic ammo, optimized for short range suppressed shooting, and lightweight super-sonic ammo for longer range shots. While initially it was difficult to stabilize the wide range of bullet weights, it was finally settled that a 1:7 twist provides the best results throughout the full range of bullet weights. Generally, the lighter weight bullets, 110 through 125 grains are polymer or ballistic tipped hunting bullets used in 300 BLK hunting ammo, 147 grain FMJ bullets are common for bulk 300 BLK range/target ammo, while the heavy 220 gr HPBT bullets are the best types of bullets for subsonic 300 Blackout ammo to use in suppressed rifles. Usually, very little, if any, adjustment to the rifle is needed for reliable function with all these types of 300 BLK ammo.
