Privi 10mm is weak. So is the WW subsonic in the pic and the WW Black Talon, and the Hydra-Shok. the WW 175 STHP is closer to full power, as are the Hornady loadings. Old Norma and new Underwood are true full power.

I am not saying any of them are bad. Just like the .357/.38, the 10mm can be useful with a wide range of loadings. But comparing the 10mm to anything else when you are shooting Privi ammo is like saying a .357 mag is weak whe you are only shooting .38's out of it.
