So I saw an article or twenty about some ammo that was debuted at Shot Show 2019, about a 9mm round (apparently also going to be made in .45 and 12 gauge) that weighs in at 185 gr and fires at 950 fps from a 4.5 inch Glock barrel, does 16" of bare penetration with good expansion and has a strange two part casing that's some steel alloy and an aluminum base. Not sure but it seems a bit gimmicky to me. I'm not super fond of steel casing ammo, and I certainly don't feel much trust in a two piece casing with questionable pressures to get that heavy of a slug down a short barrel. What do you guys think?
