Hi Ken,I worked up that load with info I was given on this forum.I tried lots of combos including different size balls, different size patching different weight powder charges and different lubes.It also took two barrels as I learned all I need to know about Pyrodex when I had to replace the first one!!!! As far as good eyes go not mine!!!! Mine are 69 yrs old, have had 2 cataract surgerys along with the lenses they put in at that time. Then there were detached retnas in both eyes and then I had a stroke in the left eye (my shooting eye) that cost me 1/2 of that eye and left my vision in what was left preety poor!!!! Its not good eyes its years and years of shooting all different kinds of weapons till I just have an instinct for when the shot is right and the trigger is squeezed. Frank
