Gonna be a smidge loose, unless by not ever having an oversize primer stuffed into them they might be tighter?

Never had 'em unprimed...yet.

Actually never had a major problem with American primers in the Cheddite/Fiocchi hulls, couple here and there a bit too loose fer confidence, quick peen with BP's tool and all good. Tighten up nice after firing anyway. Usually use Cheddite primers though as I seem to recall a test where they had the most consistant energy, would not assume that means they are going to give most consistant results in actual loads but should be a start?

YMMV,
