I tried searching for this in previous posts, but the subject is too vague, and I couldn’t find anything. This came to me in a lot of 500 loose-packed 9mm rds with 80gr lead-free fmj copper-jacket bullets. All of the headstamps were the one shown below - all new brass. I am almost certain that these are from Fedarm, and are the jacketed version of the same type of ammo discussed here in a recent thread: https://forum.cartridgecollectors.org/t/9mm-headstamps-in-natmil-fedarm-alloy-bulk-lots/16610/1. These jacketed bullets have the same type of silver metal under the jacket that the unjacketed bullets in that other thread show. This same projectile type was sold recently by the same Gunbroker seller (Shore Tactical), but only in 1000rd lots of loaded 9mm, and USAC is the only seller I can find online that seems to offer this same type of Fedarm lead-free ammo. The headstamp is a weak-struck: 9x19mm and I have never seen anything like it, as far as being a more generic version of another headstamp, but without the manufacturer stamped at 12-o’clock. I almost wonder if there is some new headstamping technology where rapid laser etching is used on a high-speed machine, and I wondered this about the new headstamps from OATH Ammo as well, which look weak and/or engraved? The case is non-ferrous, and weighs roughly the same grain-weight as any other NUPE 9mm brass case. It is boxer-primed.
Everything else I have seen previously from Fedarm / Natmil has been mixed headstamp reloaded brass.
I noticed the base of the rim seems very sharply beveled, more so than any other new 9x19 case I could find laying around:
Here is the retail listing from USAC:
