Glad to hear the 16 bore is ready to finish, Dan. That 140gr. charge is really a good one. Obviously, Swiss is a much more efficient powder than the GOEX that we are able to get here.
: Have you tired express-type sights? I find the shallow "V" with a front bead to be much better than a narrow slot and post or blade front sight.
: One of Track's Jaeger sights with one flip-up blade, re-shaped properly, would make an excellent sight for an English big bore. I do like the bead, especially for hunting. I also find it suitable for a target ML as well. This is how I finally made the sights for my .40 flinter, after some shooting with narrow "V" and blade. The rear sight was just too fuzzy to see, while the shallow "V" is much better observed.
