You’ve got a mighty fine 300 AAC Blackout rifle there. It wouldn’t be a shame if it were just a little quieter, though. Winchester loads this 300 BLK ammo to deliver the subsonic muzzle velocities that equal quieter reports – just what the doctor ordered if you’ve got yourself a suppressor!

This round’s low muzzle velocity doesn’t mean its chamber pressure is too weak to cycle your semi-auto. It’s just loaded with a very heavy 200 grain bullet, which has too much inertia for propellant gasses to force it to break the sound barrier.

Sure, this round’s slow-moving bullet will follow a steep trajectory, but that’s not to say it’s inaccurate. The open tip bullet features a fully jacketed flat base (which dramatically reduces barrel and baffle fouling), as well as the sleek profile it needs to keep its nose pointed downrange. The open tip’s good rotational stability is the product of its concentric copper alloy jacket and its form-fitted solid lead core.

This subsonic load’s bullet will not undergo terminal expansion. Its terminal ballistics are pretty much the same as an FMJ. But this American-made ammo will give you clean-shooting performance, as well as reloadable brass cases after the fact.
