With a new barrel, how many rounds does it take before you consider a barrel broke in? I know there a quite a few theories on the process, but how many total rounds do you think? I've always felt 30 ish would get it done, but have friends who swear the magic number is 100!

Some guys use Tubbs final finishing bullets to get break in done with one trip but then again others say not to so...

Unless you're building a bench rifle, the best way to break in a barrel is to clean it well when new, then shoot it till the accuracy falls off. Then clean the barrel again, and repeat.

Some bench rest guys follow a break in procedure, yes it may give them the .001" that they need to win the match at some point, but the rest of us won't notice it. They also clean the crap out of their barrels, and then shoot fowler shots, because they know that the best shots out of a barrel are the first few after it has been fowled.

That being said, we in the rest of the world won't see a difference for hundreds of rounds, mainly because no one else measures groups to .001, and we won't see the groups open up a few .001 after 50 rounds. To you and I, it will look the same.

I approached my barrel break in this way.  I ran a swab down the bore when I got it, installed it, and shot almost 100 rounds the first day.  Then I cleaned it again.  I'm done as far as I'm concerned, I don't believe in barrel mysticism.

Years ago, I took a long range ballistics class from Jon Weiler, who now runs http://www.professionalmarksmen.com/

He had the attitude that I think is appropriate.  You got a new gun, check out the barrel.  If you don't see any major problems with it, run a brush and patch through it to make sure it is go to go and shoot it as you normally would.  Basically, your barrel never stops changing.  It is always "breaking in" with every shot.  Shooting a magic combination of rounds and cleaning procedures does nothing to change the actual characteristics of your barrel except to put the wear and tear on it of the number of rounds fired and cleaning methods used.

To date, nobody has every shown that any given "breaking in method" has actually produced knowable changes to barrel.  There are lots of claims with lots of different magic formulas of shots, cleaning procedures, and cleaning chemicals that all claim to be the right way.  Given the number and variability of such claims, "breaking in" seems to be more of a religious ritual rather than a truly reliable method that produces verifiable results. 

Let me ask you this.  When have you shot a gun and said to yourself, "When this gun was new, the owner didn't break in the barrel properly."
