I am interested in fox and coyote hunting. My grandfather has been seein and hearing a lot of coyotes lately on his farm. He has 200 acres of woods and plenty of fields. I was wondering what would be the best way to hunt the coyotes. Either in the woods or on the treeline of the fields at night? He saw a coyote a couple weeks ago in the middle of the day run up through the field and past his barn. By the time he grabbed his gun it was gone. I have a .12 gauge and a .22 mag. I guess the .12 gauge would work if I hunt the woods and the .22 mag should work in the fields, correct? I was wondering if I needed more fire power for them in the field than a .22 mag. I'd like to get a .223 or .243 anyways, but would the .22 mag work in the meantime? What is a better caliber for them the .223 or .243? I was also wondering where I can find a quality cordless red lens spotlight? What about electronic callers? I was looking at the Foxpro Spitfire. Is this a good caller and is it worth the money? Would you recommend a different brand that is just as good, but cheaper? Is a rabbit type decoy a must have? How long do you typically call them for? Do you leave it on most of the time while hunting or do you just do it sporatically in spurts?

I don't know a lot about coyote hunting, just what I see on hunting shows.
But out of the 2 calibers you said, 223, and 243.
I would get the 243, because you can hunt deer with it also.
From what I have seen, get an inexspnive call, and hang a big feather from a tree limb, or from a stick, in the ground.
The feather will spin, and flip in the wind, and get the coyotes attention.
Or one of the electronic predator calls, with a spinning decoy on top.
On the coyote hunting shows, I have seen they call sporatically.
And get quiet when they see the coyote/coyotes.

What ever you do Good Luck, and post pictures.
