Only ran one box thru it - Federal American Eagle - 130g - FMJ
(actually running low on 38 spcl - eeeeek!) and it ran well. Here is a 10 shot group from 12 yards:
Then I started shooting at a bowling pin that was, I thought, 40 yards away - later found out it was 45 yards! Took a few shots...thought I was missing to the right...compensated... took a few more. Ended up hitting it on the 18th shot. I finally realized I was compensating too much. Next time, I hit it on the fourth shot. And the next two times, I hit it on the third shot.
Lotsa fun. I need to stock up on rounds again and get my snubs exercised!
