Whats the story behind breaking in a new barrel? Is it worth it? What is the best method?

Clean it well (get out all the factory gack and grunge from the barrel, chamber and lug recesses). Lube the bolt lugs. fire one round, inspect for visable copper streaks and clean if seen. Repeat until no streaks are seen after 1 round. Now fire 2 rounds and inspect, repeat until no streaks are seen. Now fire 5 and inspect/clean.
If you want the full rote methiod, skip the inspections, and do the 1 round/clean thing for the first 10 rounds, 2 rounds/clean until 30 have been fired, and 5 rounds/clean until 100 have been fired.
Personaly I sacrafice a chicken and read the entrails to learn how many rounds I need to fire before cleaning[}:)] IOW It do'es nothing for accuracy, and "might" aid in faster cleaning down the road. Your money, your time.
Some guys like a mag full of lead, I still prefer one round to the head.0 -
I do it for the reason tailgunner touched on. I see a big reduction in fouling as the break-in process is done. Once it falls off to almost no fouling for 3-5shots,..it is fine. Some break-in quick,..some take longer.
why chase the game when the bullet can get em from here?....

I do the 1-10, 5-100 brushing every 20 method....of course if your new bang stick is a .300 RUM you're in for a lot of hurt. In which case I like the last method Tailgunner described.....
We have the second amendment so that all the rest are secure....UNK>0 -
First I've heard of this , I haven't shot my Buck Mark Hunter
yet and I'm a bit of a rookie. Could you give a little more detail
in layman terms ?
Copper Streaks ?

Copper will look like stripes of rust orange. Depending on the barrel, they can vary from vary narrow (in the corner of the land/groove) to looking like the entire inside of the barrel was painted.
Use a good quality copper solvent, and follow the lable directions. Give the solvent time to work. As this solvent will also eat your brass brush and jags some discression is required when deciding if the blue/green on the patches is from the barrel or from the tools.
At a minimum you need to acquire a quality 1 pc cleaning rod (I won't get into the SS vs coated vs carbon fiber discussion) and a bore guide that fits your rifle. Avoid jointed rods and rods made of aluminum, as they will dammage to your barrel.

i am from the school that says don't do anything to it. for the final reason tailgunner says. it doesn't help accuracy and debateable as to whether it helps cleaning. i really don't see where cleaning is all that bad anyways, it is kinda fun.
I'm not an expert, but i did stay in a Holiday Inn Express last night.0 -
You can search older posts. This topic has been kicked around a good bit. Some say it is a waste of time, others follow a detailed procedure of shooting then cleaning/polishing with bore paste.
It is your gun, do what you want to do, but a conservative approach may be best.
I followed a modest version of the procedure using bore paste to 'polish' the barrel on a piece that collected a lot of copper. The improvement was quite noticable. Much less jacket material was left in the barrel, and what was there was easier to clean out. I did not see any improvement in accuracy, but it was not worse either.

We will most certainly hang separately.0 -
Not only search the forum but search the web as well. There is a huge amount of information and discussion from some of the top people in the industry. These discussions cover the various methods and justifications for 'breaking a barrel in' from new.
Gale McMillan, barrel maker and fiberglass stock fame is noted for saying that he had seen more barrels damaged from cleaning than helped by breaking in. And that break in methods were a way for barrel makers to increase their business.

When the Walthers that were police tradeins were imported, many did not look like they had been fired much, but the rifling was really worn. It appears the Germans like to clean their guns frequently, even if they are not fired.

I heard this wasn't needed on a pistol , only on rifles.

If the previous post was in response to my post, I was referring to the amount of wear that occurred on the rifling due to cleaning.
