I didn't want to hijack this thread http://www.savageshooters.com/showth...467#post143467 but it got me to wondering.

So here are my questions;

All bores have tooling marks. Aftermarket barrels will normally have these reduced to a certain extent. When we clean the bore with copper & carbon remover we tend to take a lot of the fouling away from the tooling marks. It seems to me that a barrel will be most accurate after several shots have put down be bore again. Since we have to re-foul the bore, is it logical to remove all traces copper, etc when we clean it? How clean does it really need to be?

I would like for the posters to use real life experiences (your own or talking to an barrel makers, gunsmith, etc). I can read all the speculation myself.
