[QUOTE="406pat, post: 646782, member: 13575"] I've heard of a few people having troubles with Hornady .338 brass. It was my understanding that they were using brass with a web similar in thickness to the parent case (.416 Rigby) while Lapua actually modified the internal case dimensions for a stronger web. I heard that Hornady had fixed the problem with their new manufacturing process but I think this was fairly recent and I don't believe enough time has passed to purge all of the old cases from supply. (Open to correction, this is just what I've heard through the grapevine) Maybe you have the old brass and it's stretching more on one side than the other? With that said, I'd try a piece or two of Lapua or Norma brass and do the same process of firing once and then marking up with the Sharpie. At the same time, you might want to get some Cerrosafe and make a cast of your chamber and check it on a concentricity gauge. Those two tests should pretty well tell you if it's the brass or the chamber. [/QUOTE]
