I used several 22 Mags, Browning A Bolt, Marlin 25M, Savage, Marlin Tube feed, and several different Ruger's including one heavy barrel.
I still have the Ruger Boat Paddle 22 Mag and the Marlin Tube feed. I used a flock of different scopes with a Leupold 3.5x10, Leupold 3x9 vari X-II, Burris 3x12 signature Being my favorite for calling. I also tried the 1.5-5x Leupold and hated it, then the 2x7 which I thought was marginal. I had Leupold put a single target knob on the 3.5x10's, and marked the drop at 100, 150, and 200 yards. My longest shot was on a big male at 125 yards, facing me, he fell over stiff legged.
When living in Az., I rode a Tri color, Gaited, Spotted Saddle horse. Scout could cover 11 miles in 45 minutes. We would ride along till we saw coyotes, then rode the direction the coyotes were coming from, where they felt safe. I would put a set of hobbles on Scout, or tie him to a bush. Scout would always know where and when the coyotes were coming from, and would start pawing the ground if he was tied up or shaking his head because he knew I was about to shoot. I would always get around 50 yards from scout in plain sight of him. The coyotes would come in looking at the horse, never at me, and I did wear a camo face net and gloves. When the coyotes saw the horse and I riding, they never paid any attention to the man on the horse, just the horse if no one was talking, and if the tack was not making a metallic clanking sound.
I killed 55 in one Summer with the Ruger Boat paddle 22 Mag, using the technique above in Az. Scout was one heck of a horse, he died at 38 years of age.
I wanted to add that if you ever shoot any plated lead bullets in your 22 mag barrel, the barrel will lead up, accuracy will go to pot. 40g Winchester HP is a true jacketed bullet, and I found best accuracy was maintained cleaning every 250 rounds.
