I know there are different power 10mm rounds, some are nothing more than .40 cal. I have been playing with my stribog shooting federal 180 fmj with great results. I got some nosler 200 grain bonded jhp, rated at 1000 fps muzzle velocity. It was weak, so weak it struggled to reliably cycle. It was very quiet suppressed so that's a plus but it's not gonna cut it. I'm looking for something self defensive that's full power in a hollow point. I see underwood makes good ammo, Buffalo bore also. My lgs had some hornady but it was only 135gr. Heavy, full power hollopoint. What should I look at?
