    I'm looking for a weatherby single stack mag box, spring, and follower for a custom build I'm starting right now. my smith said to get the weatherby one because it feeds better, but I can't find one anywhere.

    looked on brownells, midway, and googled around. maybe I'm just overlooking the obvious. could you guys point me in the right direction, or give me a better idea if there is something better.

    thanks again

    Go to the Weatherby site and get the number to call them, there customer service is great.

    Ask them for a 378 mag box and flat top follower, they will have it to you in a few days.

    Ok, probably another stupid question, but help me understand why a 378wby has a different or longer mag box than does a 338-378wby???

    It is a bigger longer round than the other Weatherbys (300,340 ETC.)

    If you are going to build a rifle on a 378 case and you have one of the smaller rounds
    you will probably have to mill the bolt stop slot in the bolt a little longer in addition to
    opening the bolt face. if not a 378 case the mag box will work by simply bending the
    ears on the mag box in untill they hold the round.

    Let us know If we can help answer any more Questions.
