All the rest of the parts are the same except for barrel shank size, nut size, and recoil lug size and they're easy to find so I see it as no liability either. I wish they made more large shanks but that's just me. I had both my long action magnums converted to large shank. I have no problem with the small shank for standard calibers but wish they made the large shank even for the belted magnums. May not be necessary but I like it better having thicker chamber walls for that portion that is outside the receiver ring.
