Well, I don't know if this helps any but I've recently emailed and asked about the rules and regs in Texas and this is what I got in return:
Means and Methods
Firearms
Game animals and game birds may be hunted with any legal firearm,
EXCEPT:
-white-tailed deer, mule deer, desert bighorn sheep, and pronghorn
antelope may NOT be hunted with rimfire ammunition of any caliber.
-shotguns are the only legal firearm that may be used to hunt Eastern
turkey during the spring Eastern turkey season (see County Listing).
Rifles and handguns may not be used to hunt Eastern turkey.
-pellet guns and other air guns are NOT LEGAL.
-fully automatic firearms are NOT LEGAL.
-firearms equipped with MuzzleBrakes or sound-suppressing devices are NOT
LEGAL.
-a shotgun is the only legal firearm for hunting migratory game birds
and lesser prairie chicken (see Definitions - Legal Shotgun).
