Hello all, well I finally decided on a barrel twist and length for my 45-70 build, I ended up going with a heavy 28" 1:18 / 8 groove Mcgowen with a straight taper. It is coming along and I think I am going to be happy with my choice of barrel. Still needs a lot more work on the stock and finish work on the metal.The target is in 1/2" squares. So what does everyone think so far.
