traditions site list them new at 464.00, being used i would guess around 250.00 - 300.00. as to the other questions yes. i have the shenendoah model with the same twist, shoots conicals and roundball both very well.all my rifles , austin hallick , cva kentucky, shoot the conical.
I have the Pa Longrifle from Traditions. Shoots PRB well esp. when i do my part.. Never shot the conicals although ive heard good things. If its in really good shape, not shot much, no real cosmetic flaws id say up to $350 wouild be ok if thats what you really wanted. I like my PA Longrifle. Like the Kentucky very old timey traditional looking rifle.
