IMO a pitted smooth bore is a PITA
mostly concerning cleaning .

the thing is though , you never know how pitted a barrel is , tell its clean .
rust grows like a mushroom . it starts in a small pit and then spreds out on the serface . so what you see may be alot of serface rust that will clean out .
the other thing is as long as its not to deep you can runn a hone down it and re polish .
Or you can have it reamed a couple thousands and bring the bore back to life .

but again you have to ask yourself ; is it worth the cost . if your getting the gun cheep then it probably is .
but if the asking price is at the top of what its worth without a pitted bore . then IMO you should pass if your not willing to put in more money to clean it up
