My barrel break in goes on with sighting in a new rifle, no need to waste ammo right?
I'm not a believer in the shoot one, clean one, yada yada yada, sacrifice a small animal to the barrel gods and so on.
I do the initial cleaning of factory lube then shoot at a relatively slow pace sighting in before moving on to targets and clean maybe every 20-30 in the first 100. After that the barrel wont get cleaned until I finish shooting or accuracy drops off, usually its me finishing.
Heat is the barrels enemy
