There's more case capacity in the 50-110 and that's a heat treated cylinder. The limit will be the brass, and it's Starline brass so really the limit will likely be the shooter.

Frankly, the S&W can be loaded to perform beyond the comfort level of many/most shooters. I don't know how far the owner of that revolver will go with his load development, but there's a great deal of potential there for him to explore.
