Using my Theoben .20 cal. The steel disk is at 100 yards, a few sighter shots and then a full magazine shot at it. The big steel disk is at 130 yards and I shot a 10 shot group at it. The rusty steel sheet has several groups that were pretty good, and the little piece of paper has the best group of all, it’s 12 shots at 130 yards. I really like this rifle!
