Greetings. by up north, I mean someplace as obscure as Smithers, British Columbia, Canada. Being the proud owner of several 5 screw Smiths, mostly .455,( one Brazilian in 45acp ) I find this website nicely complements the info I have being able to get from SCSW, and the Jinks book. Recently retired from the BC Forest Service, now I have time to play !!!!
