It's HSM 180 hardcast flatpoint, cci500, 7.5gr Longshot, 1.135". My test was with win brass. Chrono averaged 1199. No idea what the pressure is, but Hodgdon lists a max 8.0 gr with 180XTP. I had others loaded up at 7.8 and 8.0 gr but didn't bother to shoot them, because 1200 was my target velocity, and I hit literally everything I put my sights on with that load, out to 60 yds, .5 L water bottles. Kind of freaky. It does lead the barrel a little, so it isn't interchangeable with jacketed loads. I put it in the gun for wilderness carry. If the opportunity arises, I'll put it through a deer. If I had to deflect/stop a bear, no problem.
