I have seen alot of break in posts and was wondering if anyone had a link.  I just ordered a Stag leftty and when it gets here I would like to know proper break in.
 Thanks for the help.

The best way is to load, fire, repeat.

There are many opinions on breaking in barrels. The people who make money off selling new wore out barrels tell you to do it. The people who shoot them in matches tell you just shoot it as it is now.

if it is chrome bore, 200-250 rds before cleaning. thats all it needs.

If you REALLY want to do it, you can clean after every round until there is a noticeable reduction in fouling.  It really depends on how convenient it is at your range, and how anal you want to bw about it.  I just broke in my 24" SS bull barrel and cleaned it every shot for the first 10 and then every 2 shots until 20 rds were fired.  This seemed sufficient to me to take care of any burrs or anything that break in is supposed to do.  

One of the thoughts behind barrel break in is that there are microscopic pores in the metal of the bore and rather than have them fill with copper and carbon etc.  That if you clean after every shot that you are removing the fouling, and each successive shot will slowly push some of the metal in the bore over those pores and seal it up.  Essentialy polishing the barrel to some extent.  This is what I have read, and have no idea whether it is the case or not.  It is one of the theories out there.

This can be a hot topic.  I just read a thread the other day that got a little crazy for awhile.

Here are a few links on the subject.

i've heard from a lot of people that chrome-lined bbls dont really need to be broken in, just firea few hundred rounds and clean it.

+1.

My break in method:
1 - take firearm out of box (if there is one)
2 - read manual
3 - disassemble and do a normal cleaning
4 - Go to your normal firing range
5 - Eyes/ears
6 - insert loaded mag
7 - Shoot until mag is empty
8 - go to #7 until you have no more ammo
9 - firearm is now "broken in"
10 - go home and clean firearm
11 -  look for next purchase

No break in for chrome lined bores.
If you search the web, you will find good arguements on both sides of the break in question from top competitors and barrel makers.
If you're not shooting benchrest or NRA highpower competition, it really doesn't matter.
My opinion is the all you really need to do is remove all of the copper between shooting sessions.
I like "Wipe Out" for copper removal. It won't harm your bore and it eliminates a lot of strokes with your cleaning rod.

go to the maryland AR15 shooters site or to the Olympic Arms web page for info on barrel break in. i would recommend a break in, not just a shoot 250 rounds and clean.

Unless you are talking about an expensive fancy-schmancy competition barrel, the notion of "break-in" is moot.  Just shoot your rifle and clean it at the end of the day.

And EVEN for the super-fancy barrels, there is considerable disagreement among very experienced shooters about whether or not a traditional "break-in" makes ANY difference at all.

The break in I did was run a patch with JB Bore paste 300 strokes, change the patch every 10.  That is all I did on my match gun.


Chrome lined barrels you shoot 300 or so rounds through them and then clean.  Nothing to it.
