In the abstract it says that during the day you can use a shotgun with pellets equal to or less than .230 inches in diameter (page 44). At night (till midnight) rifles chambered to take larger than .22 caliber long rifle rimfire are prohibited (page 34). Where does it indicate that you can use a rifle chambered in .223, believe me I would love to know because I have one that I would love to use. Thanks for any help.

" COYOTE & FOXHunting hours begin ½ hour before sunrise and end at midnight, except 1) on WMAs stocked with pheasant or quail during the pheasant and quail season when hunting hours begin at sunrise and end at sunset and 2) when hunting coyote during the shotgun deer season (see below).
Coyote and fox may be hunted with shotguns, muzzleloaders and archery, as well as rifles and handguns with special nighttime restrictions (see Hunting Prohibitions). Coyotes may be hunted with shotguns using numbered or lettered birdshot (≤ 0.230 inch pellet diameter), except during the shotgun deer season (see below). Fox may be hunted with numbered birdshot only (≤ 0.160 inch pellet diameter). It is legal to hunt coyote and fox using bait, decoys, electronic or manual calls and dogs. Artificial lights are prohibited. Coyote and fox pelts must be checked/reported within 4 working days of the end of the season (see Trapping). It is legal to hunt coyotes, but not fox,
during the shotgun deer season; however the following additional regulations apply:
Hunting hours begin ½ hour before sunrise and end ½ hour after sunset.
Use of manual or electronic calls and dogs are prohibited.
Rifles and handguns are prohibited.
Shotguns and muzzleloaders loaded with slugs, single balls or buckshot may also be used.

============================
IOW - during the day, you can use rifles, handguns, archery, or shotguns, but if using a rifle at night, it can be .22LR max.
