I just bought 1000 Rem 9 1/2 primers for my 22-250 brass. These things are fighting me like a broken zipper. They're very hard to insert. I've tried both Remington and Winchester brass fired through the same rifle. I've tried my old Lee hand primer tool and my RCBS single stage press primer inserter. These bastards are an absolute bear to insert. I've reloaded this same brass with CCI primers many times years ago with no problem whatsoever. I'm assuming it's me, so what the hell am I doing wrong over here???
