The 9.3 BS and Sisk were made by or at least named for the custom rifle maker Charlie Sisk. The BS is IIRC an 8mm Mag case necked up the Sisk is the 350 Rem Mag case necked up.
The 375 Ruger case would do every thing the 8mm Mag case does. Or you could take the 416 Rigby case and make a shoulder mounted field piece. The Ruger case lets one use a larger variety of actions as it is 2.5 inches long.
Pick a case and build. Oh how we like to watch!
I want to make an 8mm with the 375 Ruger case just so I can call it the 8mmwapiti
