Because this is subsonic 300 Blackout ammunition, function can vary by barrel length, gas system, suppressor use, and magazine setup. Test it in your firearm before relying on it. Also confirm your rifle is chambered for 300 AAC Blackout, since this cartridge is not interchangeable with 5.56 NATO or .223 Remington.
