Back in November 1985, Skeeter Skelton wrote in Shooting Times: "Our first "keeper" load was comprised of a cast RCBS 32-98 grain flatpoint bullet, sized .312 and weighing 100 grains, over 8.7 grains of 2400 powder. This round made one-inch groups at 20 yards and registered 1,227fps on my Oehler Model 33. Another selected handload proved substantially more potent -- the Hornady 85 grain JHP over 9.4 grains of Accurate Arms No. 7 powder for 1,448fps and two inch groups from a sandbag rest."
A while later, he published that a "large ammunition maker" tested those loads and sent the following: "Your handload with the Hornady 85 grain bullet, fired in our pressure barrel, gave a velocity of 1,503 fps and a pressure of 38,940 psi. The 100 grain cast bullet gave a velocity of 1,263 fps and a pressure of 30,940 psi. For comparison, the Federal 95 grain lead bullet, fired in the same barrel, gave 1,038 fps and 21,500 psi."
Still later, in September 1986, Skeeter said about his Nov. 1985 article: "I believe, and still believe, that the Ruger Single-Six will stand up to this load with no problems, but I cannot -- and will not -- recommend it to others.......The little Ruger is an exceptionally strong revolver -- and the ONLY one in which I would fire such a load. My work with this gun/load combination was purely for my own edification, and anyone else who tries it does so entirely on his own responsibility."
