In an effort to cut down on cost, I've lately been acquiring some military brass to be reloaded for my AR-15. I'm having trouble with removing the primer crimp after de-priming the brass. When I prime the brass, my primers either deform in the primer pocket, leaving a useless shell casing. I'm looking for any experiences with reaming or swaging out the primer crimp. Does anybody out there have any easy to use tools that would be able to properly ream out the primer pocket to allow easier priming? I now have a primer pocket cleaners, flash hole tool and the like. None of which have the proper effect on actually removing the primer crimp. Any home-made gizmos or ideas are welcome. Thanks.
