Lloyd3,
Lining the rifle barrel of a drilling generally doesn't work out too well because it has been regulated to shoot the larger bullet to the point of impact governed by the sights. Also, a 22 Mag cartridge is rim fire, and the liner would need to be off set at the chamber end. What Works very well is an Einstecklauf( EL) (insert barrel) in the right hand shot barrel, chambered for 22LR or 22 Mag. These are adjustable for point of impact and leave the rifle barrel available for use with full loads or light, and squib loads. Common light handloads for 9.3x72R would have around a 200-grain bullet from 1200 to 1600 fps.
