    Large shank reciever.


    Other than the shorter barrel nut how can one be sure that a 300wsm is a large thread action. The picture I am seeing is not definitive.

    There is a step down in diameter in front of the nut.

    If that rifle has the original factory barrel on it and it is a WSM, then it is a large shank. It is definitely a newer rifle and Savage quit with the small shank WSM when they started the large shank, multiple years ago.

    Your right! That is the newer smooth nut and it is a wsm. Thanks everyone.
