Feel like a new contender carbine barrel. I hadn’t visited the SSK website in years. Once you sign up you can access their barrel configurator. For the 45-70 only a 1 in 14” twist rate is offered. My plan was to use this barrel for lighter weight cast boolits from collar buttons up 350 grains. In other words, this would be for quieter fun on paper targets and cans, etc. Is the 1 in 14 too fast for my intended use?
