if you need to ask for advice for an overmax load then havent been reloading long enough to do so. Overloading is a risky business and should not be lightly. I did it in some .357mag, but that was with lil'gun that gives low pressures to start with and I had another 10,000cup above my loads to get into the real max of a .357mag in a large framed handgun. accuracy dropped off fast though and i went back to the published max.
