I originally bought the 50 caliber black powder rifle and love it. However, over the past couple years I've checked the auction sights for spare barrels. Found a near new 7 mag barrel for a hundred and bought it. Shoots great! Just after Turkey season, I found a Turkey barrel for around a hundred and bought it too. Now I have a total of three barrels for this gun and all shoot extremely well. There are bargains out there on barrels and forearms if you are patient and watch the auctions. Ebay and Gunbroker are the best.
Just thought I'd throw this out there. Next I'm going to start searching for a rifled shotgun barrel.
