[QUOTE="MudRunner2005, post: 1505514, member: 12995"] I have a hard time believing that, having measured MANY case heads right above the groove, watching how pressures expand them. I've also seen lots of brass that wouldn't even hold a primer...Like completely falling out. Something like that is trash to me. I think the idea is cool, but the physics of the brass expansion doesn't seem to be in favor of the idea. Also, I'm all about saving money when I can, because I KNOW and have lived the exact definition of BROKE, but I'm not fixing to try that. More power to those that do, and I'm not knocking it, I'm just saying, I have a very hard time believing that pushing on the top of the flash hole and beating downwards onto a large ball bearing is going to do anything to reduce the primer pocket side dimensions once they've expanded to the point that primers are loose. Short of resizing the entire base of the cartridge, you'll never get solid primer contact again...And even then you'd probably be lucky to get 50% contact. Once a primer pocket stretches, the only way to fix it, is to melt the cases back down and make new brass. [/QUOTE]
