Way down yonder in the Indian Nation a Cowboys life is my occupation. And my other occupation is deer hunter. Yes, I am an Okie and you can use an in-line muzzloader, and a scope. Night vision type is a no-no not even. Red dot sights are also a no-no. Sight in for 100 yards if you are going to be hunting in Eastern Oklahoma. The western part of the state you might get a longer shot. I wouldn't shoot at anything over 150 with a muzzloader anway. Also you can shoot sabots. And like the man asked, "where is this Ti Ranch? Lots of big outfits are gobbling this state up for hunting clubs and it is something that I do not like. But I guess that I might as well get used to it. Cause the bottom line is that money talks.
