what ammo is this?

[Stainless]

the bottom markings say "F C 9mm Luger". Its stainless cased hollow points.

I think it may be Federal 147gr personal defense, maybe even Hydra-shock of some sort.

[Caster]

First off that's nickel plated brass, not stainless

Second, it looks like Federal Hydrashok. Easy to tell, is there a little tit inside the cavity of the hollow point? If so that is an immediate give away.

[Stainless]

no tit, just a deep v

Hey now let's keep this G rated

[NRA]

my guess would be Federal Cartridge Corp

Yep, that's the way my hydra-shoks are stamped. Mine are 135gr -jhp- low recoil.

Those are Federal Hi-Shok's. . in standard pressure. . 147 grain JHP. . Federal's production code 9MS. .pretty much the same thing as a 9BPLE except a heavier bullet and standard pressure instead of +p+. . .
