You could backer her down a little (ie. sacrafice 100 fps to prevent having to tinker with brass all the time). Or, get some 404 Jeffery cases and form them. Of course, you will have to get the bolt opened up a tad to use these cases. From what I am told, you can wear out a barrel with 40 of these cases.
Finally, I formed 50 300RUM Nosler cases into 338RUM cases. When I was testing loads, some of the pockets opened up a tad when I approached a press limit. Instead of throwing the brass away, I got one of the Hart primer pocket tools and have not had any issues whatsoever. Still have the brass and it works great. I have over 10 shots on each piece and my load is 101 H1000 behind a 225 Acubond for 3226 fps in my Hall Express Repeater bolt gun.
OOPs....... almost forgot..... The better the chambering quality the less the brass moves.
