300WSM Reloading Brass Question
I've been reloading for a few years so I've got a decent understanding of whats going on and how to go about things. Thing is i'm a a small bore guy and i mostly reload for my 22-250, but I have reloaded for my ex-girlfriends brother for 3 years now. This last deer season he had an issue if split necks after the 3rd reload and 4th firing as they started out as Winchester ammo.
Annealing is about the only thing i can think that would save the brass but i don't really have a good way of doing it and my previous attempts haven't gone to well.
So other then annealing what would you all recommend?
All cartridges were loaded within SAMMI spec.
cases were neck sized only so i know this is attributing to the early death of the case.
I have yet to actually see one and I'm not sure if the last firing would put the cases over spec and i could trim them down to fix, presumably only getting another reload or two out of them before failure reoccurred.
