[QUOTE="J E Custom, post: 1434467, member: 2736"] I am another one that has had nothing but good luck with Lapua brass. I can understand that problems can show up with "Any" brand of brass and long ago decided to alter my loading procedure to head off these problems. When I buy new brass, I like to use an inside neck sizer to uniform the ID of the neck, then use a good fitting turning mandrel and turn the necks just enough to clean any concentricity issues up and uniform the neck thickness. Then I set the sizing die to size the case neck to get the proper bullet tension and load. I have found that when I do new cases this way before firing, the first time, The chamber can true the case to the bore centerline and everything remains centered with uniform thickness of the neck. I have found that cases that have not been done this way end up with inconsistent concentricity when loaded because the chamber will/can move the neck centerline off center buy whatever the neck wall thickness difference is. The end results have been, better SDs and uniform neck tensions. (I do this with all brands of brass). There are good batches of brass and bad batches with any brand of brass. And this has solved these issues for me with all brands so it has become the normal way I start with new brass. As far as the primer pocket issue, I have had no issues with any new brass, but many different brands of brass that had been fired has developed loose pockets at different firing count intervals. The dents in the necks are part of a handling problem at the manufactures that may/does happen to any brand of brass and should be addressed before loading in my opinion, but as long as it does not hinder the loading process, it does not appear to hurt the brass/load performance very much. Just the way I like to prep new brass. J E CUSTOM [/QUOTE]
