big question here. [may not be the first]
thinking of a rifle build with a rolling block action. when looking into a supplier for a octagon barrel first stop was green mountain. 38-55 information gives a choice of 1-12, and 1-14. Lymann 50th data used a 1-20. this seams like a big difference. the data uses 249gr, and 355gr cast lead. i will be using cast at mid range [1600fps +/-]
would either of these barrels work for me? i can not get my head around the twist rate thing. opinions will vary, facts not so much. i would like a source that i can understand [simple] so i can get this correct the first time. are other factors that are important involved? barrel length maybe?
