Thread: Case head separation imminent

Good section and write up - possibly worth while adding that with a lot of cases if they are fired in a rifle they'll chamber back in the same rifle quite happily. In that case it's a little bit hard to use the 'until it doesn't chamber' thing to guide your headspace setup. I prefer the method of marking the case neck and shoulder and running the case into the die until the marks are just touching the case's shoulder. Then you should be just bumping the neck back on each sizing...

Could you put up some pictures of the marked cases before and after please
