ok sports fans, here is the answer you all have been waiting for: Jesse Selkirk. Ol' Jesse was a bad man that landed in central Oregon in 1903-04, he was hired to kill livestock that crossed from one side of the "deadline" to the other and was paid $2.00 a head for doing so, during the summer of '04 he killed appox 3000 sheep for the "Crook County Sheepkiller Association" and a unknown amount of cattle for the Sheepowners.
Jesse had no use for the new fangled rifles that were popular then and did his work with a 74 sharps shooting a 44-70-470 load, he would go alone into the mountains which the livestock used as summer range and spread a piece of canvas out, set up his shooting stick, wiping rod, 250 rds and a canteen of water and set to work.
Selkirk was known to have been involved in the Johnson and Lincoln county wars years earlier and it was said that he could account for some of the Oregon herders and ranchers that came up missing during the sheep/cattle wars.
I have no idea of what ever became of Jesse or his rifle but I am doing my homework on that.
