Put a patch with a carbon cleaner down it to remove any carbon from the proof loads and knock any other possible contaminants that may haves worked themselves into the bore during transportation...then go shoot! 

If it's a decent matchgrade barrel (e.g. Bartlein, Krieger etc) they've already been lapped.

Polishing, with JB paste etc will just erode your throat quicker.

Bullets do a good amount of the 'smoothing' process to iron out any burrs post reaming. Just go shoot.

As I remember I did JB my old factory Remington rifle barrel. As it was recommended to do so , since my 6br is a Louther Benchrest barrel I have no intention to JB it.

I will follow  Steve DUNN guidance for my barrel as I did with my 7mm barrel, Steve ,Laurie and Vince are the ones who have guided me on my Fclass shooting and will also guide me on Benchrest shooting.

if I can’t succeed with the input from these people then I will take up Fishing !!

Roy: Thanks for posting that McMillan piece. I have been meaning to look it up. It a waste of time and barrel life. I have always contended that if I was told to 'run in' a high dollar custom barrel I would ask for my money back. ~Andrew

A lot of us have adhered to something akin to the 'McMillan method'. I used to.  Now, I just shoot 20 odd rounds right off (which usually includes a bit of load-development) BUT I'm prepared to spend the next couple of days getting out all the copper residue. It's then ready for competition.

There is an interesting piece on the Snipers Hide forum at the moment - where the poster recommends running-in by shooting multiple rounds without cleaning - to burnish the barrel - i.e to form a hard coating.  Interesting.

The knowledge is out there - freely available. There will always be opposite opinions. No one likes the tedious 'shoot one clean' running-in process and again, it all depends on the use of your rifle.  If you're simply a hunter you perhaps don't demand the same performance as a benchrest shooter.

We all have expectations for our new barrel - if it doesn't live up to those expectations, was it our run-in procedure?  If Andrew went back to his gunsmith to complain that his new 'high dollar custom barrel" didn't shoot - I'm sure his gunsmith would ask how he ran it in.........

More to the point I would be asking the gunsmith ,  how he finished it off ....

It never would have seen a round through it. He'd have gotten it back the moment I got 'run in' instructions.~Andrew

Probably not a lot, he's most likely a bloke with a lathe in his shed and isn't a metallurgist

How he finished it off?  What would you expect him to say?

Interesting recurring question - bit like 'how/how often do you clean your rifles?' :)

Not sure about asking your gunsmith etc or going back to him if it does not shoot after the event?,

I'm just waiting on the availability of some proof loads for a new rifle, but it has already been tested by the smith using known commercial loads to an acceptable degree of performance before it leaves his shop and effectively 'run in' so I'll just shoot it when it arrives. If it does not work it's me or what I'm doing.

Christ, I even get a few example bullets cast from a custom mold to demonstrate it works - and that's a £150 item

So it is down to what you agreed with your gunsmith or supplier as to expectations and 'deliverables' - you pays your money you take your chances I suppose - caveat emptor!

Nick, read the 3rd paragraph of Brillo's reply to bobski's post on barrel conditioning, 8 posts down on this page, sound advice . I've allways run a new barrel in and never had one that shot crap so will allways do it whether it's really worth it or not!!

Hi all

, thanks for the various does and don’t, myself and Steve have bore scoped the barrel we proceeded to use a pistol rod,with bronze brush lapped with fine wire wool and drops of oil . Afterward I cleaned the barrel and some minute bits of metal findings were removed. 

Since I’ve got to zero the scope I’ve opted to fire and clean the barrel. Through the process of zeroing.

i must admit that when I purchased the rifle , it was assumed (gunsmith) that I know what to do in breaking in the barrel. Fortunately Steve is on hand and refreshed my memory.

I appreciate that everyone has there own way and there’s Not a set way to break in the barrel.
