A close friend of mine passed away recently and among other firearms he left me his black powder guns.I am no stranger to firearms but I don't know come here from sic'em about black powder guns.Among them is a Ruger Old Army pistol,a .44 cal Sile pistol,and 2 Thompson Center Hawkens rifles.I am not sure at this point what my plans are for them but is there anything unique to black powder vs firearms that need to be checked or inspected prior loading and shooting them? Thanks for any advice.
