Bad English maybe, but walking into WW-II with Mausers was basically stupid, and not something I’d anticipate from a master race or anything like that.
The British did fine with 303 Enfields. A practiced rifleman could almost match the rate of fire of a semi-auto...even with the bolt action. Having a magazine fed semi-auto with light recoil makes sense when a follow-up shot is necessary to finish the job. That isn't often necessary with a 30-06 to the chest.
