I'm sure there are threads here on LRH that have debated the effectiveness of Meloniting or salt bath nitriding gun components. I'm surprised this one has been around awhile and no one else has posted the link to an older thread.
I followed a similar one one snipershide that went on and on for sometime with shooters chiming in on increased velocities and barrel life after treating their barrels and actions. It seems to be a polarizing topic, some very respected gunsmiths recommend the treatment and others (like the one I most recently bought a custom rifle
from) will cite studies and statistics that counter the idea. My gunsmith quoted a massive study that our military (not sure what branch) undertook to study the effectiveness of meloniting for service weapons. After many years they concluded that it wasn't something that the military would benefit from.
On the other hand its hard to argue with all of the shooters who are posting their increased chronograph speeds and almost doubling the amount of rounds they put down their barrels before burning out the throats.
I know that the thread on Snipershide really focused on the process that was being done by MMI Trutec. I tried to find the youtube videos that documented the entire process, I remember watching them a couple years ago but now I can't find them. Its a really interesting process.
