Mike - good idea - however Barnes would have to inspect that rifle before your trip just to take measurements, etc. That probably wouldn't cost you very much. I would also surmise they would not and should not engage in a back-woods test like this, without having control over what was fired it the gun & how it was fired. That would be foolish for them, wouldn't it? What's to stop somone from shooting solid steel bullets just to turn the test? Although we know you wouldn't do this Mike, they cannot take the chance, and trust a stranger, thus placing their livelihood or even part of their livelihood on the outcome - as I said, rather foolish. Kinda like, stand right here on this spot and I'll drive straight at you at 100 mph and swerve at the last moment. We want to get your expression on film. I promise to swerve and not hit you.

BTW - I would not shoot any rifle off a lead sled - perhaps your double rifle is stocked to absorb such abuse.
