Do You Actually Must Break In a Rifle Barrel?


I obtained an e-mail that reads: “I not too long ago obtained a brand new barrel on my ——- rifle, so I’m following the barrel break-in protocols. I’ve finished this earlier than and it does appear to facilitate future cleansing. I nonetheless can’t clarify why this break-in process works, and I’m an engineer. Maybe your sources can shed some gentle on the method.”

First, being an engineer doesn’t give one any explicit insights, any greater than being a health care provider explains what that rash is that gained’t go away. Barrel break-in rituals are a latest phenomenon. As soon as upon a time we simply shot and didn’t undergo non secular rituals beforehand.

I don’t know in the event that they work or not, however I admit that I do the break-in dance after I get a brand new barrel, for a similar purpose that I don’t stroll underneath ladders or step on cracks within the sidewalk. Perhaps all of the taking pictures and scrubbing does work.

Why Shooters Break In New Rifle Barrels

The idea behind barrel break in is that cleansing the abrasive residue out of the bore after every shot permits the bullet which follows to flatten out or scour away all of the tiny nicks, dings, and imperfections which can be a part of most bores, making the barrel smoother and fewer apt to choose up copper fouling.

That’s the speculation. Primarily based on my expertise, I’ve doubts. Gunsmith John Blauvelt, who has put in extra barrels than most, wrote me: “On a tough manufacturing facility barrel it might have some benefit. However on a customized hand-lapped barrel it’s not wanted…. I don’t assume that scrubbing the bore with a copper brush does something besides loosen carbon fouling…. A couple of pictures and a few J-B Compound shouldn’t be a nasty factor for a brand new manufacturing facility barrel, however these lengthy sequences of 1 shot and clear for 20 rounds after which 3 pictures and clear for extra are extreme.”

I’d go additional than that. I’ve but to see a very tough barrel that was improved by any sort of break-in process. Barrels are made from metal. Bullets are made from copper, or gilding steel alloy, which is generally copper. How is copper going to put on away metal? The one factor you are able to do with bum barrel is unscrew it and substitute it with one whose bore doesn’t seem like the floor of the moon.

There’s no correlation between bore smoothness and accuracy. I’ve seen horrendously tough barrels that shot extraordinarily properly, though cleansing them was a nightmare, and when you didn’t clear them, they’d shortly lose their accuracy.

Which brings us to the ultimate level. Whether or not you break in or not, it’s an absolute fact that when you let your barrel acquire powder fouling and particularly copper fouling, you’ll shortly have a non-shooter, regardless of how the rifle began out. This is applicable to manufacturing facility horrors and the most effective customized barrels alike.
