The traditional rules for that area arn't new and can be found in last years regs.
In addition to the "Muzzleloader-Only" rules you are only allowed use a rifle or musket with an exposed hammer that pivots, loose black powder or Pyrodex and last but not least, loaded only a patched round ball projectile.
From what I have been told the reason that hunt was moved and changed to traditional is because in recent seasons there have been too many bucks killed in this part of the state and the department thinks that the traditional guys would be more willing to shoot does than other groups of shooters. I don't know if that is true or not but that might explain why they divided the unit in half and put the hunt on the smaller side with fewer deer.
It is also my understanding that this hunt will be moved to a new unit each year, I guess wherever F&G wants to put couple hundred extra hunters...is how this hunt is gonna work.
