I'd personally take a Lee-Enfield No.1 MkIII or a No.4 to war before considering a Mauser.

Remember even the Germans saw the light when it came to a good large capacity magazine even on a bolt action and they developed their Trench Magazines.

And although I have not tried it much, a Lee-Enfield can be loaded by throwing a round in the action area and ramming the bolt home. Which is handy for someone with a empty magazine on a No.4 (T) or L42.
