I have quite a bit of FC brass in .270 WSM, .300 WSM, .300 WM, and .308 Win. So far, I’m getting 3-4 shots on the .270 WSM brass and then loose primer pockets. On the .300 WSM, I get about one more shot than the .270 WSM before the primer pockets go. So far the .300 WM is on its 3rd firing and still good, same with the .308 Win.
