Shanebevel,
I don't know what you know about the 9.3x72R but to me they are a can of worms, especially if you are not a reloader. Even if you are you will need to make a chamber cast and slug the bore to determine which variation of the cartridge that gun fires . In the Double Gun Journel, Munnell wrote an article explaining three variations of the cartridge, and yet there may be more.
I have only one drilling in 9.3x72R and when I slugged the bore the land diameter was only .358 at the muzzle. Also the rim thickness was too thin to close the breech on a modern RWS cartridge.
Some of the folks on this forum are very advanced reloaders and have no concern about unwraping the enigma of obsolete cartridges but I am not one of them so my other drillings are in less confusing chamberings.
Cheers,
Roger
