Ok, went to the range today to retest some of my "accurate" loads. My 7mm rem mag, has been grouping fairly well (~.75-1") with 66.5 gr of RL 22 and 140 B/T's. so I loaded up 5 more (this was the third time Ive tested this load) and shot all 5 and got a .9" group out of all 5 shots... am I done??? Should I call it quits on the testing thing, since this is primarily a "hunting" gun?
