I have been fascinated with this cartridge ever since I encountered it in my DEVA loading manual. It appears to be the ideal solution for the problem of what to do with my H&H rook rifle, which I have had kicking around in the vault for close to 40 years now.

The original barrel of my rifle was sleeved to .22lr and numerous holes drilled and tapped in the integral rib barrel, which has been crudely cut off with a hack saw. The butt stock has also been shortened, perhaps for a young child. Cutting the barrel off far enough ahead of the breech to form a monoblock seems to be a workable solution and the 6X70R a perfect cartridge.

Any suggestions on who to get to do such a job?
