Home Forums Hunting & Shooting Custom Rifles & Wildcats Are Winchester Model 70 barrels interchangeable?

I'm thinking of building a .300 H&H using a Winchester Model 70 .375 H&H donor action.

I know that a 30.06 barrel can be re-chambered to .300 H&H and that .300 H&H only needs a 24" barrel with the same 1:10 twist, but can I take the barrel from an Model 70 30.06 rifle and use it on the .375 H&H action.

(I'm also planning to re-barrel the 30.06 action in 6.5x55SE.)

Both donor actions would be new post 2012 CRF.

Any advice greatly appreciated.
