frame and I shoot 350 grain hard cast LBT bullets in it. Montana Bullet Works has them. Stick with the loads in Gary's Red Reloading manual and you can't go wrong... Or at least you shouldn't, anything is possible I suppose. OR
are you asking about a .44 magnum load? IF so, the 305 grain LBT hard cast will do ok if you don't try full house loads and back off of the 240 loads as a start.
