I think I would trust John Linebaugh. We were talking about 32-20 one day. He looked at my 32-20 1908 S&W. Told me it would handle any ammo made since WW II and probably stuff made before even rifle ammo. He did say to keep the number of jacketed bullets down as they would possibly wear the bore a bit more. He had a couple of pre-post 1900 SAAs he shot with everything...oh he needed 32-20 cases too. Just like most of us
