Hey bigtimer, I did as you asked and went back to your July post and re-read it in its entirety.

Here's what I found:

In your first range session you were having problems getting powerbelts on target, made some scope adjustments and got one shot in the bull, but didn't verify that shot right awaywith another as far as I could tell. A little later you shot again (two shots?) that were no where near the bull.

Second range session, this timewith Noslers, youstarted to get acceptable groups but wanted to do some tweakingwhen the session was called on account of rain. I couldn't tell how many shots or groupswere fired.

Third range session, again with Noslers, you gota real nice 3-shot group. Don't know how many other groups were shot or if you got other groups close to that great one.

I'm not trying to be a smart-ass here, but if that third range session consisted of one 3-shot group it could have been a fluke. Such things happen. On the other hand, if you had two or three pretty good groups at that last session I go back to my "scope problem" theory. A scope problem could even explain the difficulty you had getting powerbelts to group in your first session.
