The bore/land diameter on the 9.3 is right at .358, the same as the groove diameter for the 35 Whelen. Might not work but it wouldn't hurt to ask though, they take phone calls if they can and they call you back if you have to leave a voicemail.
Would you consider a .375 Whelen? I know Jess does those, as well as the .400.
