I bought a Uberti 1860 Army with a fluted cylinder a couple years ago and never shot it. No reason, really, just one of those things. Anyway, yesterday I was looking at it and pointing it, cocking it, cycling the cylinder when I noticed that at the top of the oval part of the notches there is a little bit of metal nicked out. What would have caused this? Should I have this fixed before I start shooting it or just say to hell with it and put pedal to the metal and blast away?
