NO. and for several reasons. .357 mag brass is suited to the pressures intended for the .357 magnum. if you up the ante 20,000 psi you would likely melt the brass or have a severe blowout at the primer pocket. or melt the brass and have a blowout and extrude the hot metal everywhere. And thats saying the weapon will indeed hold up to the pressures. It very well may not. Just because ruger made a blackhawk in .357 max at one time doesnt mean they hold all thier revolvers to the same strength requirements. In my opinion the .357 max is better suited to rifles because of the velocity and pressure it produces. Like i have advised before, if you want .357 max performance trade your .357 mag. in and find a .357 max revolver. I understand the way you percieve this. It wasnt all that long ago that I too thought bigger was better etc. etc. etc. But it really is quite the contrary. Rest assured the .357 mag will do everything it is intended to do quite efficiently, that is why it has outlived the .357 max. I would suggest you take your .357 mag afield with full power hunting loads and kill a hog or a deer, cut him open afterwards and inspect the damage its capable of, it really is quite impressive for such a small cartridge...
