Remington Training 300 AAC Blackout Ammo 220 Grain Open Tip Flat Base Case of 200 ammo review offers the following information;This round’s projectile is completely optimized for accuracy. The OTFB’s base is flat instead of angled, because that provides the most uniform possible surface for propellent gasses to exert their energy against. The OTFB’s narrow meplat has a very small nose cavity. This is not to permit terminal expansion, but instead exists because the bullet’s lead core was injected into place while it was still molten. A form-fitted lead core like that enhances excellent rotational stability. This is the heavy-weight type of 300 Blackout round. Its 220 grain projectile is far too heavy to achieve a supersonic muzzle velocity, which makes its report much softer at the expense of steepening its overall shot trajectory.
