How to deal with pitting and how much is too much?

I heard minor pitting in bore does not affect performance, but I had never tried one.

Sorry, I take it back. Once I had a Yugoslavian M48 which came to my hand with like-new bore, and I shot corrosive ammo. I was lazy one time and did not clean up the bore immediately after shooting (only 20-30 rounds were fired in that session). A few days later, I could see rust inside the bore. After cleaning, the bore was pitted. I have to say the rifle was not less accurate after this event, because the rifle had never been accurate at the beginning with like-new bore -- the performance of the rifle could not even compare with a pistol with stock attached at 50 yards. I am not a professional shooter, but I think that factor can be phased out, because it's same me operate those guns and I paid same amount of attention.

So, still no experience. I mean, no experience on a gun that was originally accurate, but later becoming less accurate with pitted bore.

After above mentioned M48 event, I realized how effective was corrosive ammo. Only 20-30 round shooting, plus a few days of no cleaning, is enough to damage the bore. Considering battle field condition, a pistol if ever used in battle condition, it's more likely having pitted bore today. That's almost a sufficient condtion.
