If memory serves me well, the .357 was
originally 158Grn at 1550fps or so (46,000 CUP). There was a problem with the primers being 'blown' back and freezing up the gun. They lowered the SAAMI to 35,000 CUP which is where we are now.
The big frame Ruger and S&W with LONG
brrls. loaded up to 40-42,000 CUP can certainly bring back the good 'ole days in a hurry ! ! !......dewey
