If you can find it VV N110 with CCI magnum primers gets me 1250 FPS out of 158gr XTPs out of my 2.5" 66-1. That's the starting charge right out of the VV free downloadable manual and using the OAL from the Hornady manual. I was kinda shocked and N110 instantly became my favorite .357 magnum powder! That's a seriously good load and not a lot of flash either.
