Just clean it up as best you can. It takes allot of rust to spoil the accuracy of a B/P rifle. My advise buy a wooden dowel around 5/16th dia. Split its end a little. Put a small piece of emery cloth on it. Spin it in a slow speed drill and run it up and down a dry barrel a few times. Doing so will level those pits out some and make it a bit easier to load. That's about as cheap a fix I know that may work. After that its barrel liners or boring to a larger caliber.
