In Oklahoma it's seperated into 8 sections and depending on where you live in the state you can shoot anterless deer at different times. Basically archery starts Oct. 1 and goes til the end of the year and anterless through Jan. 15. Muzzleloader is the last week of Oct. anterless all week and rifle is the two weeks in the end of Nov. Rifle you can only shoot anterless on the weekends and the last day. Muzzleloader is a great time here because the bucks are running in groups and fighting a lot. Last year I rattled up five in one group.
