Ain't figgered how what they use applies to a hunting rifle?
Actually very simple--------taper is the only difference in the actual barrel or maybe fluting. Now after the Smith gets finished with it could be significant for example, I have many hunting rifles that use the same chambers and necks as my BR guns the only difference being the taper and maybe a brake. Some people like it that way some don�t but the steel with the hole in it is the same just a little smaller taper. When I have reamers made I always use them for my hunting rifles as well that way I can do the same brass preparation as my competition chamberings.
