I would recommend a .22 magnum for 95% of all pest issues. Borderlining too light for coyotes, it's perfect for fox, coon, possom, bobcat, or any other similar-sized critter. Absolutley no recoil, relatively cheap to shoot, useable with or without a scope (assuming you buy one with open sights), and with explosive-type bullets, not too high a risk of ricochet. A regular .22 can handle most problems, but lacks range and power at distances greater than about 50 yards. I have my .22 magnum sighted dead-on at 100 yards. I have a permanent target 250 yards from my front door, and at one time I could ring my steel plates with some regularity. Said all that to say that the .22 magnum will handle ranges out to about 150 yards (WITH PRACTICE). It's so much more versatile than the standard .22. I have a varmint light that clamps onto my scope for shooting at night. With the red lens cover on, it doesn't spook predators as much.
