I used to have one hell of a good time hunting coyotes in Eastern Washington, and I was able to make a fair bit change off the deal as well. We used to get anywhere from $50 to $150 a pelt for the darn things. I think a guy would be lucky to see $10-$20 today.
We used to use simple little mouth-blown calls like the two shown below. These are your classic "dying rabbit" calls. The black, bulb shaped one is just like a squeaky toy - you squeeze it to make it squeal. We would tape these to the forearm of our rifles and use them if any 'yotes were getting in real close. While there were early, somewhat crude electronic calls available back then, we always thought that was cheating.
I started out shooting them with my old M70 '06, loaded with 110 grain bullets. I soon got tired of patching hides from the exit wounds, and Remington came out with their saboted .22 caliber bullets in '06 cases - the Remington Accelerator round. I used those for awhile, and they worked great, but this looked like a good excuse for another rifle...
So I bought a Ruger #1 in .220 Swift. I used that for years, until I shot the throat out of the original barrel. It loved 53 grain Sierras and Reloder 15, approaching 4,000 fps with that combination. After the barrel was shot out to the point I could no longer seat bullets out far enough to almost touch the rifling, it sat for a couple of years. Then, on our 10th anniversary, my lovely wife (no doubt with a bit of input from some shooting buddies) stole it and had Rick Freudenburg re-barrel it with a 28" stainless 1:12" twist Lilja barrel. That's how it remains today. Its new favorite load includes the 60 grain V-Max over a case full of IMR4350, for about 3,750 fps. Absolute death on coyotes as far away as you can make them out.
So, Hugh, I believe Remington still makes that Accelerator load in a number of calibers, including .30-30. Might be just the ticket to "reach out and touch someone" if they start getting shy and staying out of .30-30 range.
