Hello ladies and gentleman. I have a semi recently purchased .35 cal FX Impact. I have everything tuned up nicely and have shot pellets and slugs. I have taken every animal multiple times over from large racoons, to possums, to yes Coyotes. Also plenty of tree rats . My question is this. In terms of Coyote hunting, I may be asking too much but I am looking to drop these things on the spot. I have tried a headshot with a JSB Hades and to my surprise it didn't down the first one I went after. Then I switched to FX Hybrids which I absolutely love for extreme accuracy as well as big time expansion. I shoot these between 950 and 970fps. They are roughly 70 grains. I did insta drop a coyote with these with a vital shot after that. However since then I have shot at I would say at least five coyotes (I do have some pretty excellent video of these). Even one where I dropped one for a half hour with three shots in total just to be sure. Then when me and the wife went to retrieve it it miraculously got up and ran off. A ZOMBIE COYOTE, only logical conclusion . I could not believe my eyes. These midwestern Coyotes get quite large, and there are swarms of them in my backyard which are a huge problem for my puppy dog. We do have a chain link fence but they can climb over this with relative ease. So the wife has a shoot on sight order when they are on our property. I uploaded a picture of what I would consider a pretty good vital shot. I even used high speed 120 fps to show the slug in flight and where it hit. Made a loud smack and looked to be in a vital zone to me. My question would be, would I be better served shooting these things in the head with say FX 83 grain domed pellets for downing instantly? These are nuisance animals so retrieval isn't vital. However I also don't want wounded animals out there. In everyones expert opinion is this animal dead? Just had to run a ways? I have done some research and know they are very very tough animals. I also have gathered that from personal experience . I have not tried headshots with the FX hybrids, thoughts? Someone told me even high powered rifle rounds can bounce off coyotes heads as they sort of create a ramp when they look at you straight on. So I am a little unsure of my shot placements and methods. Every other animal just goes down with a 70 grain hybrid to the head very quickly. In case anyone is wondering I am shooting this off a tripod in my office upstairs in my house. I have gotten good enough with the ATN balistic calc and the FX 800MM barrel to hit what I aim at. Just starting to doubt where to aim on these?
