In one of threads in the Pistols section there is some disscussion on hunting Deer with C & B revolvers. Hunting Regs. were brought up and I decided to look on-line at some states and here is what I found. These are public sites so I guess it's OK to paste em here.
Kansas:
Legal muzzleloading pistol for deer ”“ single barrel muzzleloading pistols .45 caliber or larger, that have a barrel length of 10 inches or greater and can be loaded only through the front of the barrel with separate components. Only hard-cast solid lead, conical lead or saboted bullets weighing 210 grains or greater may be used with muzzleloading pistols. Range-finding devices and optical scopes or sights that project no visible light toward the target and do not electronically amplify visible or infrared light may be used in both the muzzleloader-only and regular firearms seasons.
Texas:
Muzzleloader: Any firearm that is loaded only through the muzzle. Note: A cap and ball firearm in which the powder and ball are loaded into a cylinder is not a muzzleloader. Muzzleloader deer seasons are restricted to muzzleloading firearms only.
Oregon:
Muzzleloading firearms with revolving actions are prohibited during muzzleloader-only seasons and 600 series hunts where there is a weapon restriction of shotgun/muzzleloader only or archery/muzzleloader only.
