[QUOTE="Shortmagman, post: 1061992, member: 10723"] You have gotten some good advise, especially from Bil Johnson. I have loaded 300WSM brass from many companies and they are different. Norma brass in my opinion is the best short mag brass. I have some that have been reloaded 10+ times and the primer pockets are still tight. The problem with the loose primer pockets on once fired brass comes from two things. One Federal brass is soft and prone to loose pockets and the second thing is factory loads are very hot! When I fired my first 300WSM Winchester factory load it was too hot, bolt almost too tight to open. Norma brass is heavier than Winchester brass(I have not compared it to Federal) and therefore the volume of the brass is less. Work up the load and you can fire many rounds without loose pockets.
