I use a 22 mag on coyotes in places where a louder report may stir up the neighbors. My favorite load was the 40 gr Remington soft points followed by the 50 gr Federal hollow points. The various 40 gr hollow points were down the line with the 45 gr Dynapoints by Winchester are far behind. I haven't tried the lighter bullets much, I blundered into a pretty good supply of 40 gr bullets and wish to use them up before trying other bullets.
I found the effective range being what has been mentioned- 100 yards is about max. I prefer closer but if there is some snow I feel comfortable out to 100 or a little more as I can track them down when they run. Given a choice I would prefer a 9mm chambered carbine or similar pistol cartridge to the same distance but a 22 WMR is also capable.
