Mac,
I am no expert, and I am NOT a masochist, but if the 500 S&W is sporting 60,000 psi and can be shot with a Handi.... :shock: Isn't that beyond Marlin 1895 pressures and getting into Ruger #1 territory??? :eek:
Seems to me that at the old H&R site folks said to use the same recipes as the 1895 when reloading the Handi...
