I've got a single shot .243 Rossi. After putting on a scope, I sighted it in. I was able to get it centered at 50 yards in about 4 shots. (Just using a sandbag.) Then moving to 100 yards, the best I could do was about a 4", 3 shot group. Time didn't allow me to stay at the range any longer.
That was last year. Today I brought it back out to see what it could do. At 50 yards, I had 3 shots in a 1" circle with 2 holes touching, about 1" left of the bullseye. I moved to the next target and now I was doing a 3 shot group about 2" left and the group opened up to about 1 1/2". I let the rifle cool down about 20 minutes while I shot my 10/22. I then moved to a 100 yrd target and my 3 shot group was about 2". Moving to a new target right away, my group was about 4 inches.
Is this just the barrel heating up? I'm not a super great rifleman but I can do pretty darn good with my 10/22. Or am I just used to rimfire and my AR (both heavy barrels) that can take dozens of rounds at a time without the effects of heat?
