Well since this thread is not about breaking in a barrel!
Back to the subject. I have done two barrels now with MMI-Trutek
Trutec The company that Joe Kendrick was with.
The first one was a 7saum and the second one was a 243ai. Here is my long write up on my whole process. Scroll down to the bottom of the page of the after target.

I think that it is a must to have the barrel broking-in. I put 50 rounds down each rifle before I sent them in. They must be spotlessly clean. No carbon or copper at all. One of the biggest thing is to make sure your gun is shooting good before you send it off. No reason doing this to a bad shooting barrel. On the 7saum I saw a gain of 40 fps with the same load. Shoot the same as far as accuracy. I would only use guys that have LOTS of experience with this precess. MMI and would be the only ones I would send my barrel two. Turn around time with MMI was a week. So if we want to have one barrel done, they need to go too, Rodney at R+T customs. A in-house guy that is talking care of it all. 870-565-2589. Cost $60 per barrel with $20 return shipping cost. Turn around time is less then a week. If you cant get him, call there Arkansas location (870) 236-6920 and ask for Rodney. If you 120 Aluminum oxide blast your barrel before you send it off. Comes back a nice flat black. I just cerakoted over mine once I got it back. I don't have enough rounds down yet to know if it last longer. But it sure does clean up fast with very little to no copper. One guy that did his 243ai as well has only has .004 of throat movement with 800 rounds down the barrel.
Let me know if you guys have any more questions
