As for H-110/WW-296, in 1980, Winchester gave the max load in Winchester cases with Winchester magnum primers and an unspecified 158 grain jacketed bullet as 16.6 grains, with a pressure of 39,500 CUP and a velocity of 1610 fps from a 8-3/8" SAAMI test barrel.
I gotta believe that velocity figure is very optimistic.

www.handloads.com lists a loading with an unspecified 158gr JHP in front of 16.5gr W296, in a 6.5" barrel revolver and reports 1338fps muzzle velocity. That sounds a lot more realistic.

With high pressure comes high temperature, and with that comes forcing cone erosion.
While that's certainly true, most folks don't consider a gun worn out because the barrel needs to be replaced.
