The Win 70's that were built as WSSM's were special short actions and magazine specifically designed for the WSSM. Savage never made a WSSM so no factory option there. I would be willing to bet that your best bet would be to attempt to try a Centerfeed Setup for a WSM, but even then I am betting that the WSSM will be like the 6BR, near impossible to get to feed.

I had a 223 WSSM for awhile, never even attempted to feed with it. Used a SS follower from day one.
