What's everyone's favorite powders for reloading .40 S&W now days? I'm reloading using CCI primers and Xtreme plated 180g bullets and have been using PowerPistol but for the life of me, cannot remember why other than I have a bunch of it. I think that it's a bit slow for .40 but the muzzle flash is fun at the range. I'm thinking of trying HP38 and TightGroup. Running numbers in Quickload seems to show that they would work reasonably well for a good mid-level target load.
