Yep, LA and MS got into a contest to see which one could make the most liberal definition of a primitive weapon. I think both states wound up with the same definition - single shot, external hammer, .35 and larger.
Iowa has two M/L seasons; early and late, as well as a separate bow season. Each year the DNR has modifications but pretty much stick with these seasons.My state, Texas, has a muzzleloader only season.
MS changed this year. The old single shot rules still apply to public land but private land is weapon of choice.
Hawg, weapon of choice is only for subsequent primitive weapons days. The first one (doe only) is still true primitive weapons on all land.
