Sounds like Fred Flintstone may have made those.

You’re not far off, Allen . . . .

Just yesterday, I loaded some ammo with those very old, CONVEX primer cups!

Did the same last week . . . .went to the range . . . .and had NO PROBLEM with ignition! (No “click-bangs”)

Got CCI with the green and black diamonds.

I had a big double handful of odd branded old primers from a few estates,

Canadian brands, and some US stuff I had not heard of in a long time
federals (I think) and another brand in wood trays with a paper outer sleeve,

In the late 60s the local Skagg's went out of business and sold their powder, primers and bullets at half price. I bought all the primers and most of the powder they had left. I still have a brick of CCI small rifle mag. primers marked .69 that I paid $3.45 and some empty powder cans at $4.49.

last time I bought primers I paid $160 for a sleeve (5K) of Large Std Winchester Rifle primers. Likewise for Large Pistol.
That was back around 2015 maybe.
I was lucky I took inventory right before that "shortage cycle" started.
