This was the heaviest factory load I could round up, and accuracy was a bit better than the average for all the subsonic loads tested. Terminal performance mirrored that of the other subsonic non-expanding bullets, with deep, straight-line penetration. Reliability was dismal. The load would not cycle the AAC carbine at all, and in the JP rifle, it fully cycled the action only 30 percent of the time.
