Lots of great info here, Coyote hunting is a challenging sport to get into for sure. I Spend a lot of time in the woods hunting deer, turkeys, ducks, geese, etc and coyote hunting is the most challenging by far.
I liken New England coyote hunting to turkey hunting: go in super camouflaged, set up against a tree, and call for 10-20 minutes. If they are there, they will come in, if they cant hear you or are too weary, you might as well just sneak out and try again another day. Get in mind a couple different spots to call from and spend first / last light hitting those spots. I don't use a rifle, just a shotgun when I'm sitting in the woods. If I were to sit in a deer stand or on an elevated hillside, I might bring a rifle to reach out there, but sitting in the woods - a rifle isn't really the right tool IMO.
Deer hunters: if you see a coyote, don't be afraid to make a little animal in distress noise with your mouth - just a squeaky, whining noise - and do it just barely loud enough for him to hear. Only make enough noise so that he barely hears it, then shut up. If he's interested he'll come to investigate. Don't let coyote see ANY movement for sure, they are 10X as observant as a deer and will run for the hills if they catch sight of you sitting in a tree. If he comes in too quick and surprises you, let him pass, get your gun or bow ready and pointed at his direction, and try to gently call him back, it works!!
1. What do you use for shotgun ammo, and where did you get it?
2. That sounds is like the kissing sound you use to call a dog. Just lick the back of your hand and kiss it really loud, kinda.
