I'm in the same boat,,, if the primer is that loose,,, then its garbage...
The issue is over loading the cartridge way to many times,,, if a person wants faster ft-per seconds and more energy down range,,, buy a cartridge that can deliver the mail with out over loading...
Life is just that simple...
Go buy a Warberg,,, BMG,,, maybe a 20 mill if you really want to knock stuff down at 2 or 3 miles,,, if that dosen't cut it,,, steep it up to the 8 mile with a 72 or 76mm... LOL
80 to 90% of my reloads are in the tame node area,,, 19 to 25 reloads if not more,,, then I finish them off for hunting,,, pitching that junk on rapped replete hunting shots is a good thing...
Fat chance I'd waist my time fixing garbage brass primer pockets,,, more power to be for those that choose to shoot un-sized / unknown refab brass...
All of us that shoot for accuracy will stick to the brass sizing ideas that work """consistently"""
A 5 grade bolt,,, ball bearing,,, ball-peen hammer and a work bench wouldn't cut it for the majority of it...
Here's and example:
$1.00 per 1 brass cartridge.
$1.00 / by 7 shots = $0.14 cents per shot...
$1.00 / by 20 shots = $0.05 cents per shot...
Why would 5 or 14 cents break your bank is beyond me,,, if a person is only getting 2 or 3 shots before the primer pocket is stretched beyond seating the next primers...
You got serious issues happening,,, it might be wizer to pay attention to the bolt handle flying out of the action taking part of the shooters face off...
A few years ago 22 shooters at a shooting match got a chance to witness a near miss,,, the shooter and the folks on either side of him...
All 3 got sprinkles of brass that day...
