I am considering purchasing my first black powder rifle. I want a Revolutionary War to Civil War era muzzle loader replica that is cheap enough for me to take to the range to shoot. I know about the history of a lot of these firearms, but I don't know much about what to look for when I'm purchasing one and what to expect from these as far as maintenance and reliability. I've heard from friends that the barrels require extra cleaning and all, but am I looking at having to replace the parts constantly or will a little cleaning and maintenance do the trick? What are some good sites or stores to check out for cost effective black powder rifles? Do most of them still shoot ball ammo and how hard/expensive is it? Thank you for the help, any other useful information that I may need to know is also welcome. Again, I just want a black powder rifle that I can shoot around at the range, not an authentic mint condition collector's item.
