Need advice - I was priming some Lapua 223 brass and inadvertently inserted one of the primers in backwards - I assume OK to use a small punch inserted through the neck to pop it out?
I would do something to attempt to kill the primer first put it in oil/wd 40- let it sit for a while as some of the stuff they seal them with takes a while to soak thru . still- BE CAREFUL- WEAR EYE PROTECTION-but how much is one round worth versus the potential problems
