I have been studying this. It seem to be replacing chrome lining. It's a barrel treatment, not a coating. So it's doubles the life of a barrel & decreases friction & heat increasing velocity. I know that ARP, Glock(Tennifer), Smith & Wesson & Springfield Armory are using the process. I know you all that shoot thousands of rounds (especially steel) a year would like to not have to buy a new barrel every year or two. Also it is RustPROOF. The only bad thing is; It only comes in black. www.youtube.com/watch?v=8QjbOZAx2mw&feature=relatedwww.youtube.com/watch?v=jiegZyhd5l0This is a stainless barrel that has been Melonite treated. the right end was bead blasted then the barrel was placed on a wet paper towel covered in table salt, wrapped up in another wet hand towel and kept wet for 1 week. That was in 2009, this is how the barrel looks in Feb 2012 It has been wrapped up in the salt for over 2 years. Only the area where the melonite treatment was blasted off did it show any corrosion.Corrosive ammo or primers are made from Sodium perchlorate not sodium chloride(common table salt). These melonite barrels are very resistant to water and salt water but not corrosive ammo. After shooting corrosive ammo you must clean the barrels the same day or pitting will occur in the bore. m.b5z.net/zirw/h7c/i/u/6132121/i//melonite_test.jpgI'd like to know if Carl has looked into using Melonite as an option on BHW Barrels? Also, What do you all think about it?!

I have two barrels nitrocarburized and they shoot great. I have observed the process might add not only corrosion resistance but also faster velocity w/o effect in accuracy unlike chrome.

COOL! you got to see the process!! I think it will catch on like spray in bed-liners. Much better than chrome line. I hope Carl or some of their pros look into it. I know "H" over at ARP is selling them like crazy! Matter of fact, Meloniting - QPQ is so good with 4150 CMV Melonite. He is getting ready to stop making SS Barrels. I really hope BHW gets in on this?!!

Many of our larger customers use these processes

Many of our larger customers use these processes When I'm ready to get a barrel assembly, I'll have to PM you for a list. WOOHOO!! I already thought up a the semi-custom barrel idea of what I'm looking for.

I do not have the proof as I do not have the two same barrels one with and without the treatment but based on what I see I believe that is the case. Accuracy has not improved but also has not suffered but the spreads are slightly improved. I will have to test more to get more conclusive answers but it seems this is what I am going to do with some other barrels. Specially those for hunting & beaters to be.

1Shotzero, Thanks for your testing! No harm to accuracy & Spread shrinkage is a good thing! Can you do some crono work on it too? One of the claims is that it improves velocity. Any difference in wear? It will probably take 2-5k to notice any (Especially the throat.).

Good info.

I put the above info out because; I feel that it is the future. That it will replace Chrome lining. Taking barrels to a whole new level. Chrome lining/Duracoating is just a coating. This fuses & becomes part of the metal.
I found a place in OH. I'll have to check them out.
EDT: Have you done any more testing 1shotzero?

It was mere coincidence that got me associated with nitrocarburizing. I had a client that was in the business, and essentially all of their demand came from the oil and gas industry. After some research into the process I took them all the hard parts to a Rem 700 I was building; barrel, receiver, trigger parts, etc, and had the entire thing treated. I have no idea what the gun would have shot like before the treatment, but here hundreds of rounds later I can shoot all the clover leaves I want in 270 WSM. It comes clean faster than any non-treated barrel I have as well. If you look at the science of the process the black color comes from the metal expanding and allowing carbon atoms to fill the spaces between molecules in the metal. This means it treats the metal and isn't simple a coating on top of the metal, it IS the metal. This gives the surface a non-stick property (which is why the O&G industry love it), and also serves to preven corrosion by eliminating "ins" for oxygen to react with the iron. If I could afford it everything I have would be treated. This opinion and $5 will get you a cup of coffee.

You could set up a sideline cottage industry just getting guys parts treated on a onsey twosey basis. You and you client need to set up a subsidiary business. Greg

I have two BHW barrels that have been melonited. The first I bought from Parallax Tactical, was already treated - a 16" LTM profile barrel. The second BHW barrel I sent in for treatment with Wynn at WMD Guns. It is an 18" barrel with rifle length gas, standard profile. I also sent in my gas tube to have that melonited as well. Cost was $75/barrel and $15/tube with $10 return shipping to me, turnaround was about 4 weeks. This was the second barrel I've done with them and they both came back a beautiful uniform deep black color. Both were bead blasted finish, so the came back matte in appearance. I started a thread about it over at ar15.com www.ar15.com/forums/t_3_4/579714_New_18_build_with_melonite_treated_BHW_barrel_and_nickel_boron_receiver.html

This is a great place for all things BHW and about anything else in the shooting sports. Those sound very nice. Did you do it mostly for the wear characteristics or the visual effect? Join in as you us them and keep us updated. Greg

For me, the reason for doing the melonite treatment was to try and increase the accurate lifespan of the barrel (reduce throat erosion) - so I'd say wear characteristics. The matte black does look great though too.
At some point I'm going have to borrow a chronograph to try and get some numbers just to have some data to share/compare...
