    I currently have a montana 99 action chambered in 300 win mag with a 3.650 mag box. Does anyone know if I can have the action opened up and use a wyatt mag box for the stw?

    If you have a 3.650" box you will actually be sitting rather well with a simple re-barrel to 7stw. The 7stw rifles I've seen are throated to 3.800".
