I'm thinking that while the 8x60S might be ballistically similar to the .318 WR perhaps the starting poster is looking for the .318 ?

I gather from the answers people think the M-S rifle was not originally made in a .318 WR? Certainly I don't think I have seen one in that calibre/chambering??? Usually in a M98.

But would it be possible? A re-barreled 8x60S to a .318 would probably work, perhaps even rebored if someone would do it? The bolt head would work as is. Magazine length and feeding?
