I think I'll send off my Valmet 12/22HP barrel set to JES to see whether he can do a re-bore to 35-30. Re-regulating the rifle barrel can be done with a flat screwdriver, and since the 22 HP is based on the 30-30 case, no modification of the extractor is necessary. RCBS has dies, and I think this will make the Valmet a great thick woods deer killer with the 35cal in one barrel and a 12ga slug in the other.
