Is this 9mm
So my empty nine mil brass is a conglomeration of brass from new ammo I've shot myself, range scrounging, and a bag of used brass I bought at the range. In it all I've got a few that seem to be the right size, but nothing on the head stamp notes that it's 9mm. The markings are "WCC" "11" and a circle with a plus in it. Are these 9mm.
Also I have some other brass that are 9mm but also have a "p+" I'm assuming those are okay to use, but just thought I'd ask.
Thanks for all the help you all have offered in the past. Lots to learn.
Live well, be safe
