Ray, the best I've used are those from Green Mountain. It is my understanding that this company is now owned by Knight, the people who make those reeeaally ugly black in-lines. My latest barrel is shooting 2-3" at 100 yds with irons (peep and gold bead) and is limited to that figure by the shooter! I find a rather blurry X at that range with these sights. I shoot traditional percussion guns in organized shoots, as well as hunt deer and elk with the same.If you like black powder, I'd probably like you----------Chuck
