I used to know, but have forgotten.
Many of my cases have an embossed "ring" about 3/4 way up the case, (4th from left, red arrows point to it) it was used to identify something, but what was it?

Pretty sure it marks the bottom end of the bullet. Looking at the case bulge on the ones I've outlined, I'm fairly certain those are the bottom of the inserted bullets. I've noticed similar bulges in my own reloads, though I have yet to actually measure out my theory.

^^ Correct. Some manufacturers produced cannelured brass cartridges to prevent bullet setback. Nowadays, I think it's not as pronounced and therefore just a leftover mark for identification (IMO). Doesn't matter for reloads as you may or may not use the same bullet as the OEM.

Thanks anti-setback cannalure! That was it.
Charger,
I'm not talking about the slight bulge in the case, but the indicated (red arrows) engraved cannalure further down.
