Took the slug gun to the range yesterday and even though we had 15 knot wind the grouping at 100 yards was pretty good. This the one I made last winter and recently mounted a scope on it. I also made a scope and have experimented with it but the vision through it is not great due to the lenses which are the same as used in the 1850's or so. These are the second time I went with my GoPro and the sound came out much better.
