22 Magnum Ballistics

What is the best distance to sight in a 22 Magnum rifle so that the trajectory is never more than 1 1/2 inches high or low? And what would this make the maximum range without having to hold over. I don't have much experience with 22 Mag rifles. Thanks for any info.

Zero it at 107 yards and it will be +1.5" at 65 yards and -1.5" at 123 yards. Of course there are lots of variables, but this is on average.

See this article comparing the .22 mag with the .17 HMR http://www.chuckhawks.com/compared_17HMR_22WMR.htm

My ballistics software spits out 119 yds zero, 137 yds MPBR. A lot depends on which bullet you choose, what your muzzle velocity is, etc. I sight mine 1.5" high at 100, hold dead on out to 140-ish yds.

Mine spit out a 108 yard zero. That is using the 40 gr. CCI. I'm assuming ryalred used the same info. Looks like Scorch used the 30 gr. CCI +V. Those look all great out of the muzzle but by the time you get out past 100 yards the smaller bullets have a major energy deficit.

I'll stick with the 40 and 50 grainers. If I want flatter shooting than that it's time to get the .17HMR.

Awesome! Thanks for the info. What ammo do you guys recommend for use as a light coyote round? Light as in not my 223.

Your MPBR really depends on what load you are shooting in it.

My .22 WMR is sighted in, dead on, at 100 yards. It's good enough for prarie dog head popping out to about 135 yards, with some hold-over at 150. (Fiocchi / Armscor 45 Grain SP and HPs)

I would think that a 40 grain HP @ around 1900 fps would be fairly detrimental to a coyote. I realize he might not explode into fur, but with a solid hit I don't think he'd go far.

He'll go much farther than you might think. It's not a humane kill.

I have not shot my .22 WMR as much as some hunters on these boards, but I have still managed at least 2,000 rounds. (Low volume for a rimfire, but respectable for .22 WMR.) I have shot everything from squirrels, to rabbits, to prarie dogs, to a wounded badger.

The .22 WMR is not enough for a humane kill on dog-sized game; in the hands of the average hunter.

You wouldn't think so would ya? But the opposite is true. A .22MAG chest shot coyote can run for anywhere between 0 yards and infinity. Top that off with the fact that their think fur soaks up a lot of blood and they leave very little blood trail. Sure you will get the occasional bang flop but the majority will be runners. I've shot em with a .22MAG and I'd do it again if that's what I had in my hands when one showed up but I'd never intentionally go coyote hunting with one.

For the record, I really wish they'd come up with a round capable of "reliably" taking coyotes that runs $15 per 50. I'd pack away all my reloading gear and never touch it again.
