Thanks for all your response and input. After another shooting session,I decided to abandon the 9mm bore. It just fouled too heavily. I asked Dennis Olson to send it to High Plains Reboring. In less than three weeks it came back as a 9.3x57. Borer and chamber both look like new now.I'm anxious to give it a try in this new form, but first I need to scout out cases, bullets, and dies. If anyone has a surplus of any of this material, I'd appreciate hearing from you. Good loading data will be helpful too. Would it be inadvisable to add a Lyman 48?
