I follow the Gale McMillan (McMillan stocks) approach as discussed on 6mmbenchrest.com. I has a gun bore that was brushed to death and you could actually see and feel the damage. I choose to wear out my barrels by shooting them. Some armorers I knew in service were rapidly against scrubbing the bores of their target pistols. The Gale McMillan, god rest his soul, approach is discussed at length at multiple shooting forums.
simple cleaning of the barrel between the rounds while you are sighting in the rifle does no damage to the barrel at all... the barrel will be burnished whether you clean it or not, at least this way you are loading of the steel pores with copper and not craphas = had
rapidly = rabidly
Drat I hate that.
