Have hunted coyotes for many years, have mostly shot bolt guns, but getting the thermal itch and wanted something that could get some shots of at night fairly quick as there is lots of dogs on a ranch i have access to.
I had a 22 grendel from balwin gunworks in Illinois done. Suppressed i am running a 69 grain tmk at approximately 3300fps with accuracy. I plan to use this on some dogs this winter as well as maybe some wolves here in idaho.
What are your guy's experiences with the 69tmk on dogs and if you run a 22 grendel what loads have you played with
Calib, I have hunted and killed coyotes for a long time. For a 22 Grendel, I would not opt for a Heavy bullet for a couple of reasons, trajectory and jacket failure to open quickly. A couple of 55g bullets have worked very, very well for us and one 60g bullet.
55g Sierra, any but the blitz kings, they are too explosive
55g Sierra lead tip blitz is in a class by it's self in massacring a coyote around 3400-3500 fps***I can not stress this enough
Toughest of the 55g is the Sierra 55g BTHp
55g Winchester with the canalure is excellent also
55g Nosler ballistic tip never has failed us
60g Berger is fantastic to say the least
Speed is the killer as it sets up a temporary wound cavity with permanent tissue destruction.
Spinners, nippers, and flippers occur when you hit them behind the diaphragm, or when you hit them low.
Speed is your friend with a bullet that will not blow up on contact. You have to hit shoulders on frontal quartering shots with bullets not exploding, penetrating to the heart and lungs. All of the bullets I have mentioned will do this in spades. Shots quartering from the rear have to penetrate 12", all the bullets I mentioned with do this after breaking a rear hip joint.
I would not opt for a bullet heavier than 60g in the Grendel due to impact velocity, and see no need in a heavy bullet for coyotes unless you are shooting at some spectacular distance, which night hunting you are not.
For shooting coyotes in the stomach(behind the diaphragm) or in front of the rear legs(kidney shot), then fast 6mm bullets take over or a 22/250 AI with 55's at 4000, at least in my experience.
Back when it was legal, we hunted Mexico with proper gun permits, Etc. We killed more coyotes in two years than most people kill or even see in a life time. We tried all kinds of calibers and bullets, constantly over the years with only military caliber not allowed.
Remember the winning combo is easy:
Speed/good bullet construction/ shot placement
If I were shooting a 22 Grendel, I would shoot a 55g Sierra lead tip blitz and massacre coyotes....massacre!
