can generate pressures of about 55,000 CUP, THIS PRESSURE RANGE IS DANGEROUS EVEN IN A WELL HEAT TREATED GERMAN OR SWEDISH MADE SMALL RING M91-M96 MAUSER ACTION, BUT IN MY OPINION, CAN BE PARTICULARY DANGEROUS IN THE MUCH SOFTER SPANISH MADE ACTIONS,alot of Spanish made m93and m95 Mausers are still around that are chambered for the 7x57 cart. will chamber in a 1916 mod7.62mm CETME chamber, However a 7.62 NATO or a. 308 as a accident waiting to happen, I collect Mausers and I won't own one, From pg 85, in Kuhnhausen's book Mauser Bolt Actions, a Shop Manual 'To compound the problen above, a 7.62x51mm nato (or a. 308 can generate,it's a small ring action and they can't handle it,for long, the most common problem that occurs with these rifles is receiver lug set back, this is when the bolt lugs are literally jammed into the receiver lugs, denting them deeply, and is always caused by overpressure,and if this happens, you have a nice lamp project, Frankly I've always considered these Spanish Mausers in. Yeah, they've been tested to 98,000 psi,so what? the action was NEVER designed for the kind of pressure that a.
