I have a T/C Cherokee. The original barrel bore is pitted pretty bad inside. I was lucky enough to fine a good replacement.

Just curious how much pitting in general effects accuracy and is there anything that can help?

Id like to get bore redone but someone had tapped it for a scope mount before I got. They did a horrible job of it so couldn’t have put a scope on it if I had wanted too.

Have shot both barrels quite a few times but never really tried to see how accurate the rifle is or could be.
 
I have 2 vintage CVA rifles that had pretty rusty and pitted barrels when I got them on the cheap.
I was able to clean up all the rust and smooth out the pits pretty good.
The guns are surprisingly accurate with a patched round ball.
In fact, last muzzleloader season, I shot a small buck with one of them. The shot was at about 40 yards.
 
@boker, the pitting can be smoothed some, but probably not eliminated. The rebore would depend a lot on how deep the holes are for mounting the scope.

Look for topics on cleaning and smoothing the bore. Accuracy may be better than one would expect, but fouling will quickly accumulate in the pitting that is left after the smoothing.
 
Pitted bores can shoot quite well but foul quickly. Bobby Hoyt can reline the barrel.
 
I had a .40 flint longrifle that had pitting in the bore but relegated to the breech. Just knowing it was there drove me crazy. I knew what to do. I sent the barrel off to Bobby Hoyt and he bored it out to .45 with the nicest round groove rifling I've ever seen. It's my favorite .45 now.
