The 300 Blackout offers a wide range of projectile weights, can be run super- or sub-sonic, with or without a supressor, and it achieves full kinetic energy from a 9" barrel. Bottom line 300 BLK makes a great AR15 pistol or rifle, for personal defense or hunting. If you had to pick only one caliber, 300 Blackout would be a contender.
