Just got a new PCC and was wondering if there is really a need/process for breaking in the barrel?  Any opinions from the gunsmiths on the forum?  Hope this is the right spot for this question.

There are quite a few places that discuss breaking in a precision barrel.  I don't think it necessary for your typical carbine or pistol. Just clean after each use for a while.  

Improper cleaning ruined more barrels than not breaking them in properly. Just sayin

Pistol caliber carbines get broken in by shooting them at my house........

There isn't any proof that barrel break-in procedures accomplish anything measurable. It can have an effect between a person's ears.

It comforts people to think they did everything within their power to ease their barrel into adulthood.

Why would you shoot at your own house?

I know I'm missing something that's an inside joke but I'll bite ... PTR-91 in 308,  not nearly the same thing so YMMV.  PTR's recommendation for this particular rifle,  which may have nothing to do with your particular firearm.  First 20 rounds run a cleaning brush down the barrel after each round. After that do the same thing every mag or two.  Barrel is fully broken in after 300 rounds.


Ahh ... this was already answered on "other thread".  Yeah what they said.

One of the stories goes is a maker of stainless stele benchrest barrels came up with the concept of breaking in barrels as a means to sell more barrels.  With some benchrest calibers, the lifespan of a barrel (or at least providing the precision a benchrest shooter demands) is roughly 1000-1200 rounds before they see any degradation.  A break-in process is going to take up at least 200 rounds, so that's 200 rounds closer to the time of barrel replacement.

I have found the process of a thorough cleaning and follow up cleanings has improved heavily fouled barrels when buying a used rifle.  However when it comes to new barrels, I haven't seen any drastic "before and after" type results.  Al this extra "de-burring" and removal of machine marks sounds credible, but wouldn't it happen anyways through regular usage?

1,100 round life on stainless barrel is underperforming.
