A friend gave me a cut down Carcano rifle that needed some love.
Have you checked to see if that specific model had gain/progressive twist rifling?
The early rifle models had 22.78 INCHES twist at the chamber end tightening to 7.93 INCHES at the muzzle, so shortening the barrel might leave you with a very slow twist rate not suitable for the wide range of bullet weight/lengths.
