Re: Melonite barrel treatment
I'm having the same experience with MMI-TruTeck & Mel/Nitr as Skyking is. Took a bit longer to get my 6xc done, close to 3 or 4 weeks. Not a big deal on my end. Its a Shilen Select Match, 1 in 8 twist, that I'd has in th shop for almost 2 years. After chambering, I did the break-in. No problems at the chamber, but, had three places in the tube that were 'skidding' some copper. Took my time. Single shots, complete cleaning for 10 rds. Polished with Isso Paste, more cleaning. Watched it all closely thru my bore scope. Had very good accuracy as the barrel broke-in. Had 56 rounds total thru the barrel. When I was satisfied, I removed the barrel and bore scoped again. The corners were rounded off, at the mouth of the chamber , quit a bit. So, I set the barrel back 1/2 turn and re-established headspace. Put the barrel back on, fired two rounds (just to remove any 'rough' from re-setting the headspace), removed the barrel and cleaned it beyond clean, and packed it off to Rodney. I've only had the chance to fire the rifle 15 rds. since getting the barrel back and installing it. Before installation, I spent about an hour cleaning residue from the process from the bore. Accuracy is as it was before treatment, less then 1/2" at 100yds. No copper deposits left behind, cleans-up very easily. I should have checked the hardness before I put it into the stock, I may do that yet. I am getting together several more barrels to send to Rodney, for treatment. Time will tell as I keep an accurate round count with the XC.
