I know that all Carcano rifles (except carbines) made from 1938 on had constant pitch rifling, as opposed to the progressive twist rifling of earlier Carcanos. I also have been able to find out that the M91/38 short rifle had a fixed rate of twist of 1:8.47. Does anyone know the rate of twist for the fixed rifling in the M91/41 long rifle?
