I maintain its practical
You didn't ask if it was easy or cheap. The gun cost over a grand new ... its still the same QUALITY, and, if converted to air vs co2 for its original 10M use, I'd say it would equal many current offerings that cost more.
I originally thought you wanted it for benchrest use. LV class allows twice the power your gun puts out, BUT, its not so easy to scope your gun. If you just want a gun that is easy to use and don't want to spend much money, stick to the co2 and shoot offhand with original sights.
That said, few 10M shooters bother with co2 anymore, and the gun would only have value to a collector, and even at that I doubt it would reach half its original value.
Trade it off to a collector against a gun that doesn't need co2, or even pressurized air, such as a spring or singlestroke if he just wants to plink with it.
