I have an Austin-Halleck .50 caliber with mount and rings. Haven't shot it in years, but with Powerbelts it was a shooter. It takes no. 11 percussion caps but I have the shotgun primer conversion to go with it. This is a quality muzzleloader, but I don't have a need for it now. If you are interested, pm me, and I'll get you some pics. Have to dig it out of the safe. Thanks.
