I have a small ring 93 Spanish Mauser action. I have a .243 Win. chamber reamer that has been used once to make a sporter on a 98 mauser. I am aware that .243 is rated at 52,000psi by SAAMI specs. According to what I heard, SAAMI thinks that small ring mausers are only good for up to 50,000psi, even though military Spanish 7x57 cartridges already were at about 52,000psi. The CIP Europeans rating seem to rate the small ring Mausers at capable of almost 60,000psi, and plenty ample for .243.
Would it be just fine to chamber a small ring mauser in .243 win?
Can I save some money and not get another reamer?
I would love it in 6.5x55 or .257 Roberts, but I also really like the .243 and already have the reamer for it, cost $150 or so for another reamer.
6.5x55 Swedish is rated at 46,000psi (however it has a substantially bigger case capacity over .243)
