Like Hornady's supersonic offering, this is another .300 Whisper load that will work in .300 AAC Blackout guns. Accuracy was average in the AAC MPW carbine, but the JP PSC-11 rifle did not like this load. It could be another situation where a faster twist rate is optimal. The bullet did not expand, penetrating on a straight line through 24 inches of gelatin, and it was not recovered. This was one of the two most reliable subsonic loads I tested.
