Can't argue with that kind of success... I love to see stacks of coyote hides. I've killed a couple hundred, but skinned out exactly one coyote in the last 5 years... almost of them were shot with either the 6mm Rem or the .25-06 (toss in a few with the .375 and the WSMs just for giggles).
I hunt coyotes purely on a depredation basis, so the 6mms and 25s get the call. If I were a fur guy, I'm thinking the .204 Ruger would be making an appearance out of the bull-pen.
Sweet picture, thanks for posting it... I know a couple of guys that hammer out the pelts, your buddy has them in spades. But, that seems like a whole lot of work for $7500 gross... throw in all the expenses and you see maybe 6 grand for 6 weeks of hunting and all the prep work... I think I'll stick to depredation.
