Yes, I understand about Berdan primed.
What I am being offered is Boxer primed Lapua. My concern was if there were potential issues with it being fired out of a semi-auto. I know recovered full auto brass is useless to a reloader. I only have a couple of semi-auto rifles but they are .22LR and one Ruger .44 Carbine and thus no real experience.
Yeah, I could buy new and get on with my life but what fun is that?
