i am not sure i understand what you mean by traditions 209 slide. i am guessing you mean slide as in the bolt type? is it a traditions inline muzzleloader? and it uses a #209 primer for ignition?
i have a traditions tracker 209 rifle. its a good rifle to start if you want to use an inline. i have'nt shot any animals with it yet. but i can kill a 20 oz. soda bottle with it at 100 yards.
