First off, Frank is a desciple of Elmer Keith and can quote his books chapter and verse like some people quote the Bible! I am not kidding.
He told me he had received a phone call from John Linebaugh the other day. John had apparently been doing some ultra long range shooting with a 45 Colt Ruger SA revolver using Franks 310 plain base Keith bullet off of a rest. John indicated that he shot an 18" group at a marked 1000 yards!!!!
I asked Frank more about this type of shooting. He indicated that a gun with over a 5 1/2" barrel doesn't work because there is not enough hold-over available on the front sight. I was very pleased to hear this as mine has exactly that barrel length. Furthermore, Frank has made marks on the barrel of a gun, even at the front of the receiver, to make a reference point for extreme hold-over. What a neat idea! I'm going to bring a black Sharpie with me in case I need it. Finally, I asked him what did he zero the pistol for, and he told me 100 yards.
So, now I know what to do. I hope to fire-lap my Bisley and have it sighted in for 100 yards before I go to Billy Dixon in July!
I'll keep you guys posted on the "grand experiment".
Just thought this was too interesting not to share!

] - it would equate to 1.8" at 100 yards, 0.018" at 1 yard or 36" and a six-inch sight radius would cut that down to 0.003" - that you'd need to be able to discriminate at arms length. OK - I'll make it 0.004" since the sight radius is probably more like 8" if you add the frame length. [ even after math correction - WOW you'd have to have great eyesight! ]
