[QUOTE="J E Custom, post: 1276759, member: 2736"] Barrel straightening use to be the norm and all barrel makers had the equipment to do so. with the newer/better drilling machines it has become less mandatory and more optional. Some custom barrel makers have perfected there drilling and reaming to the point that barrel straightening can be ruled out and only an occasional barrel will be rejected due to run out. some of these rejected barrels can be drilled to a larger diameter and reamed and rifled to within tight tolerances. (Expectable within there advertised criteria). Most premium barrels are within .002 to ,005 thousandths straightness and many are so close that they cannot be measured with most of the available (affordable) Indicators. But, even with perfect/identical barrels and done buy the same smith and with the same reamer, It would be very rare to have the same load and performance in two different rifles with the same cartridge.
