I sometimes check all the stripper clips in the rifle first to make sure they all slide freely. Some rifles are picky. I wind up with 2 piles of strippers, one that works good in the rifle and one to try in another rifle later.
@slapshut you want any of these boxes before I throw them out? Gotta come to Byron to pick them up lol. They're all just cardboard boxes except the white one I figure you might want.
