PA thinks so..they finally allowed them but only in a week doe hunt in oct i think...i duno bout regualr season im not into muzzelloading....as to answer the question i dont think they are too advanced....yet...soon they might as well stop with it all and make rifle season longer...but not yet...i really dont see why people love hunting with muzzel loaders..exspeacially in PA where flintlocks are the only thing legal in ML season(till this year) i mean why hunt wit ha gun that was made in the 1800s and alota the time doesnt go off or you miss or wound your game? make another rilfe season later i nthe winter and give us another 2 wk seeason...hunt with what you want..thats the way i see it...
