Thanks DPhillips and 400 Nitro - sometimes confusing when a new round comes out. I guess my 9.5x68mm is still my wildcat - HA! It should be a factory round, though, due to 'our' ease of making brass, not having to buy special or expensive brass.
: As to the pressure, even the lowly .260 Rem is an over 60,000 psi round - 63,000 or thereabouts. I think some people mix up the CUP/PSI numbers and since we all got used to seeing numbers in the low to mid 50,000CUP range, with some writers actually calling that pounds and now seeing actual PSI numbers over 60,000 spooks those who skim instead of reading all the words.
