Are Federal GM210M the same as 210Ms? And how old are these white box primers?

[John Miuranda]

I just traded for these primers. Theyre in boxes that dont look like current Federal Match 210Ms. Current production is in red boxes. These are white.

The item also doesnt say match on them. It says match quality. The primer is labelled GM210M.

Did I eF up buying these?

Based on the product name, it seems to be this - https://www.federalpremium.com/reloading/primers/gold-medal-centerfire-primer/11-GM210M.html

But is it the same as this? https://www.brownells.com/reloading...emium-gold-medal-rifle-primers-prod79083.aspx

Guidance appreciated. I am down to my last 1000 of the red box 210Ms. Are these like 40 year old stock? Are they even equivalent to 210Ms?
