How much feeding work do you think it would take to make a 375 Ruger out of a belted mag something, 7mm, 300, 338...
I'm considering a CZ550 medium or maybe a Ruger M77 mkII. I'm also guessing that the stock will need a cross bolt and or other reinforcements.
thoughts?

I'm cleaning out some of my less used stuff to recycle into new shiney toys.

If it's just a simple barrel swap, all you need to do is open the rails a bit and get the proper follower for it. It would probably need a stronger magazine spring to go with it. Oh, before I forget, maybe some ramp work. It should be simple.
