What is it?

[Just another 22 shooter]

I honestly ask this because I don't know.
I was out at the local outdoor range today and there was probably a dozen or so of these laying at one of the shooting stations at the pistol range. I put a 38 special round by them to give a size perspective.

Interesting, never seen anything like that before. No idea?

I guess they hold 209 Shotgun primers for a Muzzle loading rifle.
