Save up your dough, and get a FoxPro X24. Them having that Coaxial Tweeter really creates realism when the recording is of equally good quality.
Just stuff it into a Juniper or something similar, about waist height or chest height off the ground... then find a good hidey spot to sit low at, that's facing towards the crosswind from the downwind side of the caller location onward. Doing this you can get them in to 20-25yds easily. And don't need a rifle, shotgun works great. But I understand you might live in a different habitat type though, where rifle is for sure needed.
But yeah for distance? X24 works great in that regard as well. I've never had to run it terribly long before they come in, if the area has them there. But on days when I'm making stands on some new location I wanted to give a try to.. it's large rechargeable battery pack could easily go far longer than most would ever need.
I've stopped using a motion decoy for coyotes, as I've had some bolt the moment they see it. At least in my "primo spot" that's always brought one in.
Another great ultra small lightweight caller is made by Pocket Prey. Runs off a 9v battery. BUT.. you hand hold it, so you end up pointing the sound back and forth to create realism... so gotta be ready to quickly set it down on your lap the moment they come into view, so your hands are ready on the rifle/shotgun.
For .223 Rem.... seriously checkout the Hornady 35gr NTX loading! It's listed as 4000fps! And on this one good sized coyote that came in when I was using the Pocket Prey... the shot was like only.. 15yds at most. MAN did he bleed! Was shocked that little 35gr bullet had the exit hole it did, like maybe a quarter. Looked like it hit bone on the way out though, so probably why.
Also it routinely brings in Bobcats. They're just a little harder to detect coming in because they're generally more cautious.
Also there's this UK outfit (
https://3dfoxcalls.co.uk/) that 3D prints these whistle calls, to emulate like Rabbit and Rodent. They don't weigh anything so you can keep it around your neck all the time, and you can play it held in your mouth with just your lips, so hands-free to be your coaxer. Those also work really well also.
