when I first got my Ruger Old Army, I was shooting it and it was sooo off target even at 10 yards, like 12-15 inches off at first, why is that? It was brand new, and is there a break in period for this gun? Because I was first shooting it with the .45 Colt cartridge conversion cylinder, and it was really hard to get on the target, is it because of the high recoil? I was just asking because after 100 rounds, I started punching 1/2 holes in 50 yds, I just don't get it???
