    Quick question: what’s the approx. CUP max for an original small ring mauser? Most of the data I’ve seen is ~45k max. I assume that’s data meant for small ring mausers. Please confirm.

    Thanks!

    44-45-46KCUP are the usual numbers one finds. Plenty will tell you the 96 should not be loaded higher, but a number of European companies do(50KCUP) load a little higher. And CG and Norma reworked the basic CG 96 actions into a civilian model called the (G) 63. 63's are chambered in both 6.5X55 and 7.62NATO/308(52KCUP). Sometimes they are referred to as a g-6.Best

    I suppose that would depend on whose standard you're looking at? SAAMI or CIP?

    SAAMI is 46K CUP (~51,000 PSI) while CIP is 380 MPa (~55,000 PSI). Nearly all reloading data available in the U.S. lists data maxed at 46K CUP. Although, in the past I've noticed Ramshot shows 55K PSI for some of their 6.5x55 loads. Vhitavouri, I believe, does as well (which is not surprising considering the slightly higher European standard).

    This is not a 6.5 answer, it is a 7mm answer. However all someone has to do is research the proof and standard operating pressures of the 6.5 X 55 cartridge around 1900, and I suspect, the answer will be the 45K max.
