Defective primers????

[AKMarty]

GM210M primers that I noticed while priming some 6.5CM. Thoughts on the viability/reliability?

There were 3 out of the first 30=10%!!

That's certainly different. Even if they still ignited, i imagine the ignition from them would be different than the rest.

I think you are looking at the color markings, not primer compound. Load one in empty case and see if it fires.

Each primer manufacturer marks their primers for identification.

That's weird. I've never seen anything like that.

No I think he’s talking about the anvil bring flush with the primer cup instead of sticking out a little.

AKMarty:

have you measured the cup dimensions to see if they differ from another lot, maybe?

You won’t see any difference.
Seen it, non issue.

Lot# of primers?

I just measured mine and the cup skirt is .115” long

Have to check when I get back home. Mostly I was noting the red substance. Dye? Sealant? I hadn’t considered the anvil depth. I just assumed that the anvil gets pressed in during seating if it sticks out at all.
