I agree. I am sure he can take care of it. I have seen a couple of rifles a Krieghoff, and a Chapuis, that were rechambered from 458 to 450 3 1/4 without proofs. They were both for sale and the asking price was what an untouched rifle should be. Around $8,000. They never sold and even at $5000 the Chapuis is still for sale. I lost track of the Krighoff.

Nobody know who did the work on the Chapuis, if it was reregulated and even if it was done correctly and that they would get a safe rifle. Thus it is untouchable. I offered $4500 for the Chapuis on the condition that I would pay for a reproof. If the rifle failed than I would get all my money back. The owner refused. He still has it 3 years later.

Maybe he has little confidence in the rifle as configured.
