After you clean it up with steel wool take it to the range, wipe it out with a dry patch, and pop a few caps. Then load it and shoot it. See how it does. When the old timers had a barrel too smooth the accuracy would drop off. They would pee into the bore and leave it overnight and clean it in the morning. Then it was ready to hold a patch. Point is, a little bit of roughness won't kill it and the more you shoot and clean the slicker it will get. Good luck and Be Well, RZ.
