Nope, the frame isn't strong enough, I tried a 300WSM, didn't work, too much case head thrust. The TC Encore is stronger and it isn't strong enough.

Yes, frame flex is one problem, underlug set back is the other. Any magnum rifle chambering, short mag or otherwise has too much case head thrust for an SB2 frame. The 270 and 300 WSMs share the same case with a case head of .555" and a SAAMI MAP  65kpsi.  I solved the underlug setback issue, but there's not much that can reasonably be done to the frame to strengthen it by us mere mortals.  ;D

Bullberry used to offer short mag barrels for the Encore, but they recalled them and quit selling them.
