I can offer some insight as to what will likely happen if they do go this route. In both MS and LA, once they allowed the centerfire cartridges in, muzzleloaders became virtually worthless, because almost everyone chose the new option. Then supplies became hard to find for anyone who didn't swap weapons. 38-55 , 35 Whelen, .444, 45-70, and probably a few even less common cartridges are about all you see in the woods now.
Then, in MS, it went to this... "During any open season on deer with primitive weapons after November 30, a person may use any legal weapon of choice on private lands only, if the person is the title owner of the land, the lessee of the hunting rights on the land, a member of a hunting club leasing the hunting rights on the land, or a guest of a person specified above."
In my opinion, it appears that they are headed toward any weapon all season, which really threatens bow hunting. And that will be a real shame! And, if it happens there, it can happen here. All of these agencies attend the Southeastern Deer Study Group meetings each year. And, you can bet that that gets the wheels to turning when they hear stories from other states. From an enforcement point of view, simple regulations make sense. I spoke out against this change, for all of the reasons I just wrote about here...
