I've been making some loads for my 7mm Rem Mag with 64gr. of H-4831 powder and 139gr. Hornady SST bullets. I started with a group of 20 new cases and I'm now on my 5th re-loading for the same 20. The primer pockets are not loose,there is no visible signs of any kind of problems with the cases. Should I call it quits with these 20 7mm RM cases and start a new batch, or are these good for a few more reloadings? Thanks.
