[QUOTE="Bart B, post: 1812517, member: 5302"] Very good, according to top ranked competitive shooters and others who use good conditions and standards. For example, if the barrel starts out averaging 1/4 MOA and X number of shots later averaging 3/8 MOA, 50% bigger, time to rebarrel. Varmint hunters may use a larger group reference starting out with 1/2 MOA then rebarrel at 3/4 or 1 MOA. They'll get near twice the barrel life as competition folks. 3 times the group sizes and round count for big game hunters. 4 times for service rifles used in combat. It's popular for people to use the smallest group shot as the accuracy claim. Doesn't matter to them that all the other groups are up to several times bigger. None of the long range single 5-shot or 10-shot record group holders also hold the six 10-shot group aggregate (average) records that are much bigger. The current NBRSA 1000 yard six 10-shot group aggregate record has its largest single group 7 inches plus with a 5.96" average. [/QUOTE]
