Blacknitride metal processing

[Gina1]

Hi Guys

After wearing out the barrel in my 6XC, I'm now in the process of getting it replaced. It lasted 2,000 rounds with excessive throat erosion. The rifling did not look that good with a borescope,.
I'm thinking about getting the new barrel (after it is broken in) blacknitrided through H&M Metal Processing for longer barrel life.
I was wondering if anyone on the forum has has had it done to their barrels and how it worked out?
Questions...
(1) is throat erosion and wear reduced ?
(2) When it came back from processing, was there any change in accuracy?
(3)Easier to clean ?
(4) And anything else to be aware of.

Thanks for any feedback.

Look under gun project questions and there is a newer thread on the company you are asking about and costs and results.

Normally you want to nitride a barrel BEFORE you break it in. Every barrel is going to be different but what I can tell you for sure is that it will clean easier, last longer and never corrode. More than likely you will need to bump up your charge a couple tenths to get back to the same velocity.. I put together a few AR uppers and the only barrel that I will install now are nitrided barrels. In my opinion, better than stainless or hard chrome. I have used specialized cutters for years that have been nitrided, some are over 10 years old and never been sharpened where a tool steel cutter would last maybe 6 months before it needed to be re-worked. It is a great process if done correctly.

I learned the hard way everything must be right before you nitrite

If there are any burrs left from chambering, or rifling in the barrel they will be hardened and be permanent... and they will eat you bullet jackets.

If it makes your barrel that hard will it ever break in??

Do you know what you are really doing when you say break in a barrel? I think you have my email address Regina. Actually I can send you actual military results with Melonite(Nitried).
