Tis true. 'Smiths will tell you they replace more rifle barrels that have been cleaned improperly or too aggressively than they do shot out barrels. Very few ever shoot enough to wear out a barrel but plenty clean it enough to ruin it it seems. Truth is some copper in the bore is a very good thing. No benchrest shooter would approach a match with a barrel stripped free of copper. Generally they prefer to have 20-30 shots down the barrel because that's when accuracy is best. You can usually go 100-150 rounds between cleaning with no measurable loss of accuracy. Any imperfections in your barrel such as tooling marks are filled in by copper. Strip it back out and those tooling marks are degrading accuracy again until the barrel gets fouled. And the old ideas about breaking in a barrel seem to be fruitless at best and can be harmful at worst. Many experienced shooters now feel it to be a waste of time. Copper is your friend until it accumulates enough to shrink bore diameter. Then it must go.So when it comes to cleaning less is often more.

Using aluminum cleaning rods from the muzzle is not good on the muzzle end of the rifling. If your not cleaning from the breech.....then you should use a bore guide that will prevent the cleaning rod from contacting the barrel.

My 220 Swift growls at me when I clean it. Always shot better dirty. That barrel has been on that gun since 1949, but I have rarely shot it in the last 30 years

So many different theories !!!!
Copper fills in the tool marks . What about not removing the powder that is burnt to the rifling that is like sand paper ?
Or the powder built up in the throat of the barrel ?
I am not saying this is not true but why is it if you are looking to buy a used gun we always look down the bore to see if it is shiny and clean ? We do this to see if the gun was taken care of ,right ?

Powder residue in the bore is pretty much a non issue. The reason I look down a bore in a gunshop is I'm looking for wear (cleaning rod), rust, a dark bore, pitting, worn rifling, or any other glaring errors I might see. But not how clean it is. I'm always hoping it was never cleaned much unless it's an old military rifle that would've seen corrosive primed ammo.

I have heard people talk about shooting out a barrel. I laugh to myself. Most people don't shoot enough to shoot out a barrel. Ego gets in the way of most things it seems.

I'm at least the third owner of my 1958 model 70.The previous owners were target and groundhog shooters.I have no idea how many rounds went down that barrel.Since 1990 I've put about 50 a year through it.Killed 2 deer with it last year.

I've shot out a barrel. It takes thousands of rounds to do it. But if you have a .257 Weatherby mag barrel life is only 900 rounds. Some of the other overbore magnums have similar life expectancies.

I have a 1915 Swedish Mauser in 6.5 x 55 Swede that I don't shoot much more. When I got it I bot headspace gauges for it. The bolt will close on the "NO-GO" gauge, but not on the "Field Gauge." It's still safe to shoot and I'm shooting rabbit fart loads from it when I do shoot it.
I do wonder how many rounds have gone down that one!!
