I'd like to know too...What's wrong with once fired?
Well when you visit an outdoor range and you watch a guy shoot his rounds and place the spents back in the original box of 20. Then watch him him toss it in the trash you know they were new. Been collecting brass since 1980s like that. Never have I had an issue. Kinda easy to know new from reloaded several times as well. Just trying to save you hassles time and money.I have a hard time trusting that they actually were only fired once. Most say they were policed at indoor ranges or ranges in general, I won't police my brass if it's close to the end of their life. I would assume others do the same thing
Lol I know how to remove a military crimp. I have both an RCBS casing prep station and a Lyman primer pocket kit. But I tend to prefer the Lyman over RCBSOP must be very new to reloading. I have some but it might have crimped primers which would really have him wondering.
