Bill,

I'm going to have to agree with 400NE on this one.

The 9.3x74R is not a problem in the US any more, and it is on the increase. Ruger is now chambering that caliber, so I fully expect an American ammo maker to start producing it. The Speer 270 grain bullets are bonded and dirt cheap. Aside from that bullet, you have a rich selection from other suppliers. Not a problem.

The 9.3 is an excellent round. I suspect you would gain nothing by your modification.

Wildcats turn most people off. If you decide to sell, you will suffer.

Just my $0.02 worth.
