My cousin picked up 100x pieces of adg. It has the smallest capacity I've observed. It's tough stuff though. Roughly half to 3/4 grain less than peterson. I found the peterson to be better quality.ADG makes 22 Creed brass and it's pretty good stuff. I believe it's also a tick on the thick-ish side so it may have a slight reduced case capacity over some of the others but I can live with that if the quality is there and it means less prep work and lasts longer.
