[QUOTE="25WSM, post: 2645582, member: 38048"] I have found that in my 40 yrs of reloading that loose primer pockets very seldom even leak with loads that are not over pressure. When the pressure comes through the flash hole the primer expands in the pocket and seals it. This is what the primer does on tight pockets too. Im very sure the little pressure my thumb uses to push the primer in is not what seals the 60000 psi gas in. I know some guys that shoot benchrest and wont throw their brass away till the necks split. And 6 ppcs are run very hard. They will use a drop of super glue or nail polish to hold loose primers in their case. I watched a guy bend the bottom of the primer cup with pliers to keep his primer from just falling out of the case. No leaks. Much less blown primer. Takes quite a bit of over pressure to get a primer to leak. It takes way over to get a primer to disappear. I had a guy bring me his Remington 700 that locked up. When I finally got it apart and the bolt out the case head had flowed into the extractor recess. I sent it to Remington with the brass and they gave it the ok to use still. I asked them how much pressure that round had. They said over 100000 psi. That right there shows you the weakest link. Primers. If they are gone you went way over. If it leaked your still way over. But I can say I’ve never had a primer blow because it was loose. Watching those old timer br guys made me cringe sometimes but man could they get those guns shooting. Shep [/QUOTE]
