[QUOTE="Tikkamike, post: 518395, member: 22242"] Let me start by saying I am no barrel expert by anymeans, however I have an extensive back ground with fabricating and heat treating aircraft parts. that being said I disagree. Not completely though. I agree a consentric rifle from end to end will induce accuracy however the fact that factory barrels (all to my knowledge) are NOT heat treated and stress relieved, which means as things heat up the "grains so to speak" of the iron which have been moved around with all the cold working are all moving and expanding. in different directions. Since it is tied in to the rifle on the breech end you see all of the movement on the muzzle end. which causes your point of impact to walk. Now with a concentric action, bolt, threads, chamber bore etc.. and a properly stress relieved barrel you should (in theory) be able to shoot without your point of impact changing of course you still have to deal with imperfect brass and all those other variances in your ammunition and of course changes in bore dimension from heat expansion whatever factors happen to come into play in that specific situation... so YES it is the barrels fault.. weither its entirely the barrels fault or not changes from rifle to rifle.
