Anyone care to replicate shooting @ 600 paces??? I'll drive the Bus to the Shooting Range....

35 years ago when we were on our farm I had two, 500 yard ranges, depending on which pasture the cows were in. My oldest son and I regularly shot revolvers at 500 yards. With a steady back rest with the revolver supported between your knees, just as Keith describes, and you learned how much front sight to hold up, hits on a 2' X 3' steel target ran 3-4 out of a 6 shot cylinder with an occasional 6 for 6. Back then that called for a little celebration and a draught of "Ol' Group Tightener". The two revolvers we used most were a Ruger Blackhawk in 45 Colt and a Colt New Frontier in 44 Spl. Both carried 7 1/2 inch barrels.
I am inclined to believe that with a single shot pistol results could be even better.
We didn't need a bus, we walked to my shooting bench, about 100 yards from the back door.
