AR10 .308 Break-in process
- Thread starter FA Duk
- Start date
What’s this break in stuff? Never done it. Clean the gunk out of the bore before you first shoot it, then go to town.
You can burn ur gas port and it can move. Also maybe a little faster and easier to clean. I know when I spend 800 on a tube I want to get every once of accuracy out of it
What kind of barrel? I have NEVER done a break in process On a quality made barrel. I use almost exclusively Bartlein and I’ve never had any accuracy issues that weren’t accounted to me.
Just shoot it. Never had any accuracy issues.
If you really feel like you must break it in just do what the manufacturer tells you to do.

This video will assist you with the correct barrel break in procedure
Because it's a complete waste of time and money
Break in is a waste of time. Clean it when you first get it AMD then go to town. Don’t mess with it until the Accuracy opens up a bit or if it gets rain/dirty.
You know how many Fudd’s I’ve seen ruin their barrels by over cleaning? ?

Wether I buy a Bartlein, Kreiger, or Brux I prefer to use their break in method. Seams to me the manufacturer would know better than a bunch of internet gurus.
End thread!
Closest thing I do to a break in process is not run hot reloads till barrel has finished speeding up.
Of course you’re going to burn your gas port. There’s hot gas going down the barrel. As far as moving, hows that going to happen? It’s a hole drilled in steel. Not like it’s going to get pushed further down the barrel and take up shop there.
They also sell barrels for a living, so of course they want you to use a bunch of solvents and fire unnecessary rounds. That way you buy a new barrrel sooner.
I don’t think some of these guys have heard LLs opinion on it or maybe it changed. Whatever, free country (sort of) I’ll do it my way.
I’m shooting the rifle anyway so no unnecessary rounds. As for “a bunch of solvents” nothing but hoppes 9. The companies I listed have a reputation as the being top tier in terms of accuracy . I’m guessing their reputation means something to them . It literally takes a few minutes and I’m shooting anyway so no reason not to.
Push a couple patches soaked in denatured alcohol down the bore to remove any residual oil and junk from manufacturing followed by some dry patches and then go shoot it.
Barrel break in is stupid. A barrel gets broken in by bullets passing through it, not patches and brushes so the shoot one clean one method really isn't going to do anything. It also takes way longer than the typical 10-20rd's of most break in methods for a barrel to be fully broken in. With that said it's pretty common for a barrel to foul a little at first especially factory grade stuff, when/if accuracy opens up clean and repeat. I'll typically clean after the first range session of 20-50 rounds and then again around 100 and by then it's usually pretty well smoothed out if it's a top tier barrel. I usually won't clean again until 500 or so unless it starts acting weird when the barrel speeds up which happens sometimes and then I'll clean to eliminate that variable before revisiting the load/ammo.
I don't go overboard cleaning at the first intervals either. A couple wet patches of bore tech eliminator, wait 5 mins, repeat, wait 5 mins, patch dry, swab the chamber and it's good to go. No need for a brush to come out until the 500 round cleaning and even then its just a few passes with a nylon brush.

So you honestly think that you know more about the barrels and break in than their actual manufacturer ?
It doesn't hurt and the high end mfg.'s usually have some sort of break-in procedure. Lilja barrels come with one I know, so do many others. I suppose with CHF chrome lined barrels it's probably not as big of a deal though.
It's usually something along the lines of 100rds, clean after each round for the first five, then after each five for so many rounds, ten after that, etc. Not a full clean, just a couple patches usually, some say to use a brush for those first few. I think the idea is to fill in the imperfections in a new barrel more uniformly?
I'd call the mfg. and see what they say.

you honestly don’t think the manufacturers don’t provide it to satisfy those who want to fiddle around with their new toy instead of going out to shoot it?
Where is the BEEF!
Someone show me the testing results provided by any manufacturer that breaking in a barrel provides some type of accuracy or longevity benefit.

Maybe you could post the link for us since you are familiar with it?
Sounds like you’re both talking about port erosion but, based on the way it’s described by @ChitownCopper, I’m imagining the hole literally and quite magically moving from one place to another along the length of the barrel, haha.
Right or wrong, it’s Good stuff

Now lets look at it from a different perspective, suppose you have a custom rifle made. It could be a bolt or a custom gas gun.
After the rifle is built it is range tested. Do you think the builder is going to do a shoot and clean routine?
I don thin so Lucy.

Erosion of the port or erosion of the throat, Both will effect accuracy. Rate of fire for both will have more impact on erosion than barrel break in. The minutiae on here is mind boggling sometimes. Don’t buy a borescope or you’ll be rebarreling every 500 rounds.
