Hello, There is a T/C Contender barrel for sale in a wildcat cartridge. The owner is deceased and left the information in the picture. I'm under the assumption that I would have to get custom dies made and maybe even a chamber cast from a gunsmith. Also my biggest worry is that this cartridge pressure is too close to the limits of the contender, even might be more than an g2 frame can handle. What are everyone thoughts on the limited information?
