Thinking of picking up a cheap Stevens for the build. Im awful handy around the machine shop, so anything that way isnt a problem (have a full machine/weld shop in my garage).
The question I have is that I want the gun to load from the mag, that is important to me. Will the 338 RUM load from the mag without extending it? I sounds like the Egde will not, without some work.
Would I be better off with the 7mm rem mag or 300 Win mag as the donor action?

Thanks for the help guys,

Stu
