attn BHW Forum: Barrel break in question?

[arnewbie]

Is there a specific new barrel procedure that should be utilized with a BHW P3 Barrel during break in?

[everrest]

Here is a link to wmbuck's review of the 264 LBC. He state cleaning every 5 round for the first 60 shots.

Thanks for the post, I had the same question.
That's a great link.

Decided to move this topic here to the AR section and sticky it, as it's a fairly common question.

Yes what is the procedure?

[Deleted]

Cross posted from our FAQ Section:

Our break in procedure is as follows:

5 rounds of copper jacket bullets, clean with non-copper removing solvent, clean with patch, repeat process for a total of 60 rounds.

We recommend shooting a good quality copper jacket bullet.


Secondary Note: We strongly recommend the USE OF FACTORY AMMO when breaking in your barrel.

For my 24 inch AR 6.8mmspc barrel I bought here,
I swabbed my bore every 5-8 rounds for the first 100 rounds. I just used a couple patches and FP-10 or whatever lube oil (not solvent) that I happened to have at the range with me.
Now 200 rounds later, it is smooth as a mirror. and comes clean with only two or three patches.

my 308 looks mirror-like and its never been fired! Can't wait to say I've put 200rds through it.

Does anyone have a BHW barrel that they have had melonited (nitrocarburized)? I'm curious of how the polygonal rifling works and what differences it would make vs. standard rifled barrels being treated.

Opinions vary, but it is supposed to be the equal to chrome lining the bore without the uneven thickness issues of chrome. It also blackens the steel and provides corrosion protection. A Rockwell C hardness of near 70 is achieved.

Glock slides and barrels have a type of nitrocarburization treatment for reference.

I've not seen one but it sounds like you would be a perfect guinea pig for this one, err ...I mean pioneer ,

I have never had a barrel done though the Black Star stuff sangs it's song to me once back when I had the $$'s.

I have enough rifles so I can alternate and not wear one out. If I had only one or two this might well be an option to explore.

Meloniting barrels came up a few months back as an email inquiry. I've heard Carl discussing it and he seems to think that it would make the barrel brittle and increase the chance of it actually blowing up on the user. :\

I personally can't seem to find any hard facts out there on the process' pros and cons--just a lot of hearsay. The interest has been there for us to do them over our current blacking process, but we haven't bit the bullet on it yet, so to speak. If anyone has some articles or studies, we'd love to see them.

From what I've gathered, the process could adversely effect the heat treatment of the barrel steel (the salt bath nitriding reaches a temp. of around 1100 degrees Fahrenheit), but if the heat treatment was done at a higher temperature then it should work fine.

Here's a thread from another forum with more information, discussion, and a couple videos: www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=2653056
Most seem happy that have had it done.

Thank you for the information! I'll pass it along

You are welcome. If BHW doesn't want to commit to a batch, and the associated charge, I know of an employee of a frequently used company that they allow to moonlight and melonite QPQ individual pieces/parts. Unless his pricing has changed, it was $60 for one barrel and $20 for return shipping. If you want his contact information, let me know.

I have been searching for a barrel that is:
- 6.5 Grendel
- Polygonal rifled
- Fluted
and...
- Nitrided

I understand completely that it is not your responsibility to support barrels that have been nitrided/melonited/etc after the sale. That said, I am definitely planning on nitriding the next barrel I buy.

Given that fact, is there any way to make a productive experiment out of this for you? I'm volunteering as guinea pig, in case this is an offering you are considering integrating into your lineup. Perhaps there are certain aspects you would do differently, knowing at the outset that the barrel is going to be nitrided.

A modified break-in procedure might be in order for example; one focused on removing as much carbon and copper as possible. The reasoning being that deburring should happen prior to the nitride, but the copper can still "season" the rifle afterward.

Any thoughts?
