RE: Which caliber to complete this trio
If you hunt in open areas that shoot long distances, then I would say either 22-250 or .220 Swift.
If you hunt in woods, I'd go with a .223 Ruger Carbine or, if you'd rather keep bolting, then get a CZ bolt-action 10-rounder in 7.62x39,don't remember the model name of it.
Ordinarily, I'd recommend the .243 Winchester, but, seeing as you've already got a 25-06,a .243 would exactly add muchvariety to the mix, now would it?
One last thing, and I know this might begoing toofar, if you can find a Ruger 10/22 in .22 WMR, then get it, it's not made anymore, and it'dmake a fine varmit gun, may not be the best for coyote, but I think you could use light 25-06 ammo just fine for coyotes, couldn't you?
