[QUOTE="J E Custom, post: 620821, member: 2736"] Sorry BH not trying to start a ****ing contest ,but I will have to disagree with you on this one All good buttoned rifled barrels are double stress relieved. once from the mill as the last operation and once after all drilling and rifling is done by the barrel maker. When an order is placed the barrel maker then contours or tapers the barrel per the customers needs and /or flutes the barrel. On cut rifled barrels one stress relieving is all that is nessary because there are no new stresses induced. If anything this troubles me more than the barrel maker doing the final stress relieving, because the mill has less responsibility for the finished product that the barrel maker, Dan Lilja has a good FAQ section that explains this in detail (It is under the fluting questions). This is not a debate about which method is better (Cut or buttoned rifling) just to clear up the perception that one can be contoured and the other should not. In truth any barrel not properly stress relieved whether from the mill or the barrel maker should not be turned ,fluted or contoured. So if you purchase a premium barrel with eather type of rifling there should be no reason that you could not re-contour or flute if it is done right. And in many cases it will or can improve the performance by making it perfectly concentric to the bore. J E CUSTOM [/QUOTE]
