The only primer problems I can recall are very old factory loads, especially one batch of ancient Gevelot paper hull 16 ga shells with odd non-standard primers that looked like like a extra large rifle primer, not a more common 209 battery cup type. Made in the 1960's, they have about 25% hang fires and misfires. I still have a half dozen boxes. I use them for trimming tree branches in my woodlot.
I also had a bunch of misfires with ancient Winchester Western 7x57 ammo from the 1950's or so. So old that there is nothing to blame.
