MW,
I got a chance to shoot today. I used three different loads. I started with military surplus ammo, and fired 1/4" groups, then I tried my handloaded 53 gr. Sierra HP Match with three different powder loads, and the best I got was again 1/4" groups. Then I tried Hornady 40 gr. V-MAX moly handloads, and the groups jumped to 1/2". These were all shot at 50 yards. I learned two things today, the first being that the gun is much more accurate than I am. The second was that it likes the cheap ammo, which is fine by me. I almost forgot to add that I experienced my first failure to eject. It was with handloads at the maximum charge. I don't know if this was an ejector problem, or the brass was stretched out from the load. I'll clean the ejector, and avoid the max loads which didn't group well anyway.
