The Cimarron wouldn't get off the X ring can't tel where the first one hit and the last one hit. The 1866 wouldn't move off the X ring the 66 has a flip up sight dead on at 100 yards and dead onm at 150 yards. It was a long walk oput to 150 yards and the X s no more. I decided to stop where I was at lol. I figure the only place I had to go was down.
