[QUOTE="cdherman, post: 2183351, member: 12282"] Woa, Woa WOA. They got a PROOF round that was right at 65,000 PSI. Modern rifles are (6.5 Creed for instance) get proof tested at around 79,000 PSI, and was we know, run around a 65,000 PSI max. This gives some wiggle room before the brass just starts to liquify under the pressure. So don't confuse the two. The M96 and M94 Mauser actions are legitimately, the very best small ring mausers ever made. This is due to a lucky demand that the swedes made -- they wanted the rifles made using swedish steel. Iron ore in sweden has throughout history been well regarded. This is thought to be due to naturally occuring cobalt deposits which makes swedish steel better. BUT ITS STILL inferior to modern steels. Loads for the small ring were kept around 47,000 PSI. Even "modern" European CIP specs only take the swede up to 55,000 PSI. Please, please, please no one start running high pressure rounds in M94 or M96 Mausers. Yes, you might have a gun that is lucky and has just the right steel. But your gun is over 100 years old, has never been proof tested to 79,000 PSI, and might also be suffering from age related metal fatigue. [/QUOTE]
