Federal 215m primers

[Lefty7mmstw]

I've done plenty of by hand handling of primers on older equipment I used before I got my own. Wash your hands first and you won't have trouble. I've gotten no misfires from oil in thousands of rounds loaded on that equipment. I still go by hand for test loads when I don't feel like breaking out the primer flipper and tubes. Heck, sometimes I break out the old lee seater, which is basically a recessed holder that you tap the primer in with a hammer using a rod ran through the case to transfer shock. Works fine if you watch what you're doing.

in the op's case, if a round has been struck in the primer, but didnt go off... does that now make the round more sensitive go going off by accident?

I've loaded hundreds of thousands of rounds over the last 40 years from every company and have never had a single primer not go off.. your seating them to deep or they are touching some oil somewhere along the line.. and that oil includes your hands!!
