With a standard magazine box at 84mm (divide by 25.4 to get inches), I don't like cramming long cartridges into the Mauser. To my mind, for long rane hunting, the standard mauser platform is ideally suite to the .284 Winchester, 162 grain Amax at 2900fps. You can just get away with the .30-06 which is a good-un but the sleeker .280 rem, throated and loaded to a COAL of 87-88mm to avoid powder cramping with heavier bullets, is just too long for the standard action. Obviously, if you get the magazine altered, your options open right up.
I don't have any problems with accuracy from the mausers. I just don't like bedding them, fiddly in comparison to the M700- but thats just a work/time thing. Am accurizing one at the moment for a client.
