I just posted a couple of pictures on the bragging board of my gun and also a comparison of the 45-70 and the .17 HMR. I think if I put my 2X Luepold on the 45-70 barrel that it should be a great gun at about 100 yards to maybe 125 max. before you start getting into quite a bit of drop ... I was also checking my TC reloading manual. They only list Hornady and seirra bullets ... This barrel might be the HUGE hammer in my arsenal!
