I found a chart. 9.3x57 is 44,000 CIP ppsi. 9.3x62 is higher, 9.3x64 is a lot higher.
.30 Super Belted is 53,000 CIP ppsi, I am surprised it is still listed and under the newer system at that.
But it was transmogrified to .300 H&H Magnum at 62,000 CIP ppsi. There is still the .300 Flanged at 46,000 CIP ppsi.
.416 Rigby is 47.000 ppsi CIP but SAAMI lets it go to 52,000 ppsi. The old value of 41,000 CIP CUP sounds better.
