I was deriming some 22LR brass last night and decided to derim some 22 Mag brass while I had the press set up. I went through the same routine of lube on the outside of the brass and and a little on the inside punch and figured I'd nock out the 150 or so I cases I've accumulated over the last year.
This was not the case. I had an average of about every third case blowing the top off. Turns out, Winchester does not make a case that can go through my dies without bowing the top off. There was also some CCI and a couple of Hornady's, but EVERY Winchester Super X brass busted.
Btw, when there is a blown off cap in the inside of your new formed jacket, and you heat it with a propane torch, it will build up pressure and send it self off like a rocket. This happened to me, much to my wife's surprise, while she was getting some meat out of the freezer. What are the odds....... I'm just glad it didn't hit her.....
