Short action magnums shank size

I have a small shank SA that I wanted to barrel in either 300wsm, 7wsm, or 7saum. Doing some searching here it looks like for the 300wsm using a small shank could create issues. I can't find much on the 7s but is it safe to assume the same? It'll be a hunting rifle so reliability is very important

Savage went to the large shank size shortly after they started offering the WSM and RUM's in their rifles in the early 2000's. The larger diameter of those cases results in a thinner barrel wall in the chamber area which makes it more prone to swelling given the higher 65kpsi pressure rating of these rounds. The larger shank diameter puts more material back in the barrel shank to make it stronger and more resistant to swelling. Several have built WSM's on standard shank actions, but if Savage saw fit to up the shank size and tool up/inventory another size barrel nut and recoil lug you can rest assured there was good reason for it.

Thanks J. Baker. That's great info and makes sense. Well I guess I might as well find a long action and go with 300 win mag. I guess there's worse problems to have
