This 300 AAC Blackout cartridge is loaded with a 150 grain bullet – the reason for its supersonic muzzle velocity and consistently flat trajectory. The closed tip flat base sounds alien, and it is indeed not a very common bullet. That said, it feeds, flies and penetrates exactly the same as any analogous full metal jacket. A flat base is an accuracy-enhancing feature. It doesn’t retain the bullet’s velocity as effectively as a boat tail would have, but it enables the propellant gasses to push extra uniformly against it. The CTFB is nonmagnetic, so it’s compliant at all commercial ranges. It’s also non-expanding, so it’s an inadequate choice for deer-related pastimes.
The CTFB’s cannelure keeps it securely seated in its new brass case. (The gray around the case’s shoulder simply indicates that it was properly heat-treated at the factory, not that it was reloaded.) Burn up all these rounds’ noncorrosive Boxer primers and reload them yourself!
