Check and see what the rate or twist is to the rifling along with slugging the bore.
Wright shows the X74 @ 19.4 tons.
Mike, I think that would surely have to be a misprint.
There is no way that the service pressure of the 9.3X74R could be that high.
Kynoch currently lists the .375 Belted Rimless Magnum at 19.5 Tons, and it is a 62,000 psi cartridge.
The 9.3X74R is rated at only. 49,000 psi, which I would expect would be somewhere around 16 tons.
