I commented on the low Kit Carson and Jim Bridger rear sights from Track of the Wolf in the Liver Eating Johnson thread. The original Carson sight is low, and the front sight is also then quite low. Track's sight is a close copy of it, and their Bridger rear sight is the same height at the notch, just wider for a 1 1/8" barrel. Here is the Carson rear sight on a copy of the Carson rifle I built last spring, and targets showing 50 yard impacts.
I aim with the top of the blade at the top of the "notch". The top of the notch is .255 above the barrel and the front sight is .200 high. The groups below are about 2" low at 50 yards, and I'd have to file the front sight down .025 to bring them to point of aim. I don't like that low a front sight, so I have to make a new rear sight.
These are targets I shot at 50 yards, rest, for loading data velocities. You can hit Control and the + sign to enlarge the photo. The first target, I aimed at the bottom left and the shot hit very low and the next one in the same hole, so I then moved to the top left target. That is 50 grains of Goex 3F. Then 50 grains of Goex 2F, and on the top right, 80 grains of Goex 2F. Bottom left, 80 grains of Olde Eynsford 2F, but I ran out of my linen patching and had to use a different kind, which loaded very hard and one blew. Last two were old pillow ticking.
These were weight-corrected measures for each powder, and notice that the Olde Eynsford gave 221 fps more velocity than the Goex 2F. I don't know what difference the patches made. With 100 grains of OE 2F and Goex 2F, the OE is about 100 fps faster with the same linen patching.
