[QUOTE="tim_w, post: 1451059, member: 11132"] I think the fact that many barrels have been fluted and or profiles from blanks and a number have won BR competitions at the national level should speak to if its a real world issue on premium high end barrels.. In a perfect world I agree 100% having all profile and fluting done prior to final dimensional lapping etc should give the highest degree of assurance the bore dimensions and striaghtness are at the tightest tolerance but that is not always possible. On a slightly different area of fluting; wasn’t it AI, years ago, that did testing of fluted vs unfluted barrels and found that all fluted barrels showed more movement from cold zero point of impact than nonfluted. They used lasers on barrel reciever and scope to measure movmenet as the barrel warmed up. My only question about that was if they were using button cut or hammer forged barrels. Either way hunting is a ideally a single shot and always on a cold bore and shooting comps are almost always on fully warmed barrels so.......but regardless I did find the testing and results back then interesting data points to consider as I will usually take scienfitic testing over ancedotal reports in most areas. As long as I feel I can trust the integrity of the testers and their methods. [/QUOTE]
