Demi-human
maybe likes firearms a little bit…
Them little suckers like to cling to the decap pin sometimes,,, I've 'reseated' a few spent primers on my LNL AP before
Usually easy enough to feel when it happens, but awful hard to deny when you see one later in your ammo can at the Range ,,,
Aha!
A more simple explanation is the more likely one, no magical bouncing primers.
Depending on the loading, I may or may not notice an extra case or missing bullet at the end.
It just seems a shame to ditch a bunch of primers if we can pin down the cause to simple error.
