The barrel I sent to J.D. is a 358 JDJ. Second trip to the range it disassembled a Burris 2.5x7. I shipped it back for repair. Third trip, it stripped the mounting holes in the barrel. I agree the steel bases and rings are to heavy for the handcannons. I had a Warne steel base and 3 Warne steel rings mounted on it when it stripped the holes. I talked with a local smith about doing the work, and he wouldn't touch it, so I chose to have SSK do the work. Is a $100.00 a little pricey? Maybe. But if you can't keep a scope on the barrel, then what is the point. Just my thoughts.
