It really should. Quite a few people have built small shank 338 EDGE rifles and other RUM based rounds as well, and report great success. Same goes for the WSM based cartridges, I have had a 300 WSM on a small shank, and currently have a 6-WSM wildcat on a small shank. No issues. As long as the barrel has a heavy contour around the chamber area you are good to go.
