Quite frankly I believe you are wrong. "most factory are button rifled,...". I don't know where you would have gotten that, but no- most Factory Barrels are hammer forged, The Vast Majority of Remington, FN, etc. The idea that a hammer forged tube is not as accurate, or can't be made to last as long, is a myth propagated by story tellers (to be kind), FN's barrels 10-15000 rounds and still hold 1MOA or better. Your statement about the factories run 10 times more barrels before changing their tooling, than I guess a small shop, is a puzzle! Almost no small tube makers are making hammer forged barrels, but just to clear the air, how often does let's say Remington change their Hammer Forged tooling, and would you suggest they cut that number by 90%? I'm not sure how the speed of rifling is causing the bores to be "sloppy". Are you saying that a hammer forged barrel, let's say one of FN's SPR tubes is sloppy because it may have been manufactured faster than a Douglas barrel? Can you elucidate a little on this subject ?
