Doesn't the 375 Ruger have a .532" head size?  Same as the 375 H&H?  Why wouldn't it work?

The 375H&H has a .511"-.513" case head depending on what drawing you use, the 375 Ruger has a .532" case head, rim size is irrelevent to pressure. Bolt thrust, or breech thrust in this case, is dependent on pressure and internal case head area. Both the 375s have a SAAMI MAP of 62kpsi, but the large case head of the Ruger makes it unsuitable for the Encore, MGM lists it as bolt action only.

Ah yes, I forgot that thrust is measured from the area of the case head within the case walls.  What was I thinking?!?
