I recently purchased a new Remington 700 in .300 Win Mag and I've heard a million ways to properly break in the barrel. Shoot 1 shot, swab the barrel then shoot another, etc. Any suggestions on how to properly break in/season a new rifle barrel?

I do it with a box of shells. I usually reload so I just buy a factory box of the cheapest shell I can get my hands on. I usually fire one shot, then clean the barrel after each shot for the first 4 rounds. Then I fire two rounds and clean it after each two shots for the next 6 rounds. Then I fire two strings of 3 shots and clean after each 3 shot string. Then I finally fire a four round string and clean it good before I head home. I don't think that there is a true exact science to it, but this works well for me and ultimately gets the job done in one box of shells. Hope this works out for you and good luck!

I've heard many way's and reasons for new break in. The whole point is to take the edge off of riflein??? Most good barrels (quality) are just about as clean as can be. I do a dry patch after 1st. shot. Then again after 5 shots. Don;t know why I do it this way just me I guess. I've talked to many guy's about this and everyone has a different way. The best advice I think I got was 1- shoot 2- shoot 3- shoot....later

I'm not an advocate of the "break-in" procedure. Simply clean the bore and then sight the rifle in and clean it. Shoot some more the next time at the range and clean it...after a few range sessions your rifle will be "broken-in" without all the muss and fuss. I often wonder how we (and our barrels) ever survived the "dark ages" before all this high tech barrel break-in process was deemed essential.

Your right. My new factory rifles went to the range sight in then shoot a group and clean at home. My 2 customs I did as I said above. Most new barrels settle into nice groups after about 50=100 rounds imo. It's the ol sayen Don't fix somethin that anit broke. Over thinkin!!! Just Shoot. Greatmines think alike....later

Even custom barrel makers can't agree on the "proper" break in procedure. For the most part its merely speculative and there is no real way to know if a break in routine affected a barrel positively or negatively. Anymore I don't bother with it.

If you take a little care to properly break in your barrel, you will have many years and thousands of rounds of accurate shooting and easy maintenance, treat your rifle like you do your most valued tool as one day it might be.

And to compare the quality of machining on a custom barrel to that of your typical factory barrel is like comparing Honda cars to Corvettes!

Really is shooting and cleaning your new rifle that big a burden.

None of my guns ever made it to a gun rack. They all shoot just fine. I clean them regularly. Normally after every range trip.

If you have no back ground in machining or metallurgy you would not understand, and if deer rifle accuracy is satisfactory to you just blast away.
If you think Remington core locs shoot great, blast away.
And if 100 yards is long range, by all means blast away.

If you want more out of your rifle, then put more in to it.

So...what ya say'n there...bawanajim....I've been around the block once or twice, never "broke in" one rifle bbl. and I'll put most of my hunting rifles against any. Oh, and yes I'll be shoot'n my horde of Core-Lokts for deer until I'm room temperature. My rifles give me everything they got and then some....they're just wait'n for me to get better..

They say even a blind man can take a wizz and still hit the floor most of the time.
And if core locs work for you, thats even better, I wouldn't shoot the empty cans from a case of cheap beer with them.
Some people are happy to hunt ugly with dogs, drive foreign trucks and are satisfied with mediocrity, I'm just not one of them.

I have three rifles that shoot very well, one is a Ruger,one is a Winchester and one is a Weatherly, all are capable of incredible accuracy that most could only achieve with custom rifles costing thousands of dollars, and of course shooting ammo that cost more then a box of swisher sweets.

It's funny how my Toyota Tacoma TRD Off-Road package V6 still gets me anywhere I wanna go, my Browning A-Bolt goes bang has killed over a dozen deer with Federal Power-Shok



I must be doing something wrong

I'd like to be educated as to why exactly I need to break in my factory, and custom barrels. Apparently I'm uneducated on the subject and I've been shooting thousands of rounds for nothing more than the noise. All these fancy terms like "metallurgy" and "machining" must mean your an expert, so educate us...

I could use some tips myself.

Just today I modified a RCBS 7RM FL die into a 30-338WM, I was too darn cheap to spring $60 give or take on a new one.

I'm always open to better and easier ways doing such things.


Oh, barrel break in? Naw, I have better things to do with my time or at least at 63 the time I have left!

If you research it you will find 1 known name that was against it. Gale McMillan (deceased) has 1 article he was quoted over 10 years ago and it is often quoted as a rebuttal against barrel break-in. But to me it has a tone of a personal vendetta against a prior colleague. It has no technical basis, more of a rant against the other individual.

For those that have an interest in learning something about breaking in a barrel below are a few current links. I'll also add from first hand instruction that Darrell Holland, Kenny Jarrett, and Wayne Van Zwoll recommend barrel break-in. If you buy one of their custom rifles they do it for you.
