Breaking in a barrel

Blckhrn
I can't believe it. After all these years, I have never had a new rifle until now. I would like to break it in properly because it is a precision rifle. It is a Remington M700 Stainless Steel with the 5R Mil-Spec barrel in .308. My questions are first of all what kind of ammo should I use to break it in with? I have 150 rounds of military rounds from India that I got from cheaperthandirt.com. Are these rounds suitable for break in? I will be using match grade as well as loading my own, but i did not want to waist good ammo on such a task unless it is necessary to do so. Second, How many rounds should it take to break in the barrel? Third, what is normal break in procedure? Thanks for the help folks. I will submit a range report in the general discussion forum when I have one available.

    What is the rationale for cleaning between shots when breaking in?

    Something like after 1rd for 10 afer every 2rds for 20 after every 5 for 30-50rds. after 10rds for 80 then clean after every 100-200rds
    Search new barrel break in on google for sure
    Many people say it doesnt matter, but police weapons specialist beg to differ

    Removal of copper fouling from the tooling marks, while allowing the pasage of the bullets to smooth out the marks.
    The goal is to end up with a barrel that fouls less and cleans up easier. Some people claim it improves accuracy, but that can't be proven one way or the other.

    Some guys like a mag full of lead, I still prefer one round to the head.

    chrishiher puts you in the ballpark. If you search you will get variations of the same. Also comments on using a very mild abrasive bore paste. Not like valve grinding compound, more like a soft abrasive polishing paste....which is what you are doing...right ?

    To do it or not ? You are willing enough to ask, so do it. As long as you stay within reason, it sure won't hurt.

    P.S. The 'Fire - Lapping' practice of firing hand loaded abrasive bullets has a pretty strong opposition. I agree.

    If we do not hang together,
    We will most certainly hang separately.

    x-ring for tailgunner. I don't buy the accuracy increase theroy, but I DO buy the fouling reduction properties of breaking-in a barrel.

    why chase the game when the bullet can get em from here?....

    What tailgunner and justC said. I haven't seen any conclusive proof that a break in period increases accuracy either. I have definately seen improve in getting a smoother bore with less copper fouling to clean by using the break in slow method.

    The theory is that you are 'polishing' the barrel. It allows you to take out the tiny little marks that steal a microscopic piece of bullet jacket every time you fire. Which when they build up they put a minute amount of pressure on the bullet which gives the bullet a different harmonic as it goes down the barrel. I think it makes a difference for sure reducing copper buildup, which in turns leads to a tiny bit better accuracy, hardly noticeable by most standards. But, if you are an accuracy extremist....you'll go to obsessive lengths to obtain every ounce of potential accuracy. I do it to all my barrels.

    We have the second amendment so that all the rest are secure....UNK>

    What is the name of the copper fouling solvent I've seen here?

    You might mean Blue Wonder, It is well thought of by many here, but so are a number of other products.

    I don't break in, and I have no trouble cleaning guns. It certainly cannot hurt if you don't get too aggressive, but I am not convinced it is not more ritual than functional.

    If you are going to be cleaning so much be sure to use a bushing/rod guide.

    I have a remington rifle that was made in 93 as every other remington I personally have owned built in this time period you can see chatter marks from the manderal I suppose it looks rough and when you run a tight patch down the barrel you can actually feel what I see gun shoots ok but I think it would shoot better if I could smooth the barrel any ideas (how about those coated bullets ) let me know any ideas thanks Marty
