I have an old milsurp which has a pitted bore throughout. How much does the pitting affect the accuracy of the rifle? Rifling is still strong and rest of rifle is in great shape.

Thanks in advance

I have had varied experience with pitted bores. My Braz. Mauser keyholed but kept on the paper and my 96 Swede was fine after I put some rouge on a couple of rounds it helped improve the accuracy. Cheers, Dave
 
As the two gentlemen above stated, depends on the individual rifle, I have a sporter P14 that is very accurate with handloads, but has a terrible bore, pitted puts it mildly. The main problem with pitted bores is that most of them foul very quickly and accuracy suffers sooner than later. bearhunter

Just curious, what's rouge?
 
I have a Finn Mosin that's pitted to heck, but the rifling is still decent and it shoots quite well.
 
Rouge is a fine grit polish, I think it is 600 grit, but do not quote me on that. It can help take off the high spots in a rough bore. Use very little and then wipe off, or your pressures can go through the roof. Dave
 
I had a Swede with a pitted bore and it would shoot great on the first shot, but if you fired 3 shots in a couple of minutes, accuracy went all to hell. Let 'er cool down, fire another, and it was dead centre again.
