My earlier reply from above From above.

"I think that 10b will do you a favour as it will force the barrel profile and give more mass between the hands. If anything you may have tribulations making this heavy enough for caliber.
Barrel makers can usually calculate the finished weight of barrels for any given profile."

"Have you considered the number of rounds that will need to be fired to regulate this? Maybe 100 plus over a few days because you have no starting point for reference. That is a bastard with a .600. Not great with a .577 either. That is not to discourage you but it would be a damm shame to do all the hard work and have it hospitalize you. There is a standard 1850 fps load and that is the one I would regulate for, rather than the 2050 load.
"

I think that it is in a nutshell. Theoretically, yes you can, but I think it will have to be ".600 light" How it would handle may be problomatic, but if you want a .600 for the fun of owning one then it is a relativly cheep way to get one. It will not be a Holland or a Rigby, but it could be fun within realistic expectations
