there is another thing to consider with the mauser, and that is what is referred to as mauser breeching. the whole case up to the extractor groove in supported by chamber. with remington breeching, an overload will leave tha case looking like a belted case, as part of the case head is unsupported. this offers more potential for a gas leak. again, sensible pressures are recommended. the dakota is like a m70, but with mauser breeching - the best of both worlds. bruce.
