If you switch to Peterson, ADG, etc you'll get more out of them. Peterson Long brass is a touch longer and headspaces off the shoulder not belt which greatly reduces how much the brass is worked when sizing. It's expensive but factor in the potential for extra shots and maybe pushing it a bit harder and the math works out....girl math applied to reloading.

Didn’t even know this was a thing thanks for posting itI was in your same boat right before hunting season. I was looking at Peterson, and the reason I was looking at peterson was that they offered a 300wm Long version and normal 300WM brass. The long was a longer case, not much, maybe .015" but what it did was help out with head case seperation. The reason I'm mentioning this is that they also were making 7mag brass the same way. At the time it was hareder to find. But Peterson did make a 7mag long version. I eventually gave up on it and picked up about 110 unfired new R-P brass that I'm using now.
