Bought a 20 year old Pedersoli that had never been fired from a person in Arizona. Rolling Block in 45-70. When I got the rifle - the barrel was short chambered and not headspaced. My cartridges stuck out of the chamber 1/4 inch. The bore measured .450 and the groves measured .462. I had to send the rifle to Lee Shaver and pay 250.00 to have the rifle rebarrelled. If you find an old Pedersoli, check the barrel prior to buying.
