H&M looks like a real good company that knows what they're doing. No offense to MMI Trutec because I have heard many great things about them, but I can't seem to get ahold of them or get a email reply.
If you want info on the MMI process, call Benchmark Barrels. You must deal through them or one other "sub-contractor" that MMI deals with regarding treating barrels.

You can call and deal directly with H&M, however, you will probably want to work through your gunsmith in the process because anything to be treated such as barrel, action and trigger, must be disassembled prior to sending it in.

Re: Melonite barrel treatment

All dippers and barrel makers are not equal.

All my Benchmarks were dipped prior to a shot being fired through the barrel by me. They are the smoothest bored barrel I have ever shot.

I have seen some barrels take a lot to break in so in my opinion breaking in those barrel would be sound advice I guess.

I had two factory barrels done before they were shot. One was lapped by Benchmark prior to shooting and one without lap. They both shot .5 or less when I got them with the handlapped 300 RUM bugholing.

Thanks Mark, I did not know that......Rich

Well, I sure like that idea better if it works. Taking the barrel off and on is not my idea of a good time if it isn't necessary.......thanks/Rich

Rich, unless MMI has changed their process, you must still remove the barrel from the action, especially if that action is one they will not treat.

Neal, On the factory barrels, was there a difference in fouling and cleaning between the one lapped and the one not lapped?

Re: Melonite barrel treatment

There is a big difference between a factory Non-lapped barrel before and after nitride regarding copper.

Savage barrels nearly all shoot quite well. They also foul. Once nitrided there isn't fouling.

Another example: For the past two years I have been working with Benchmark 3 groove 224 barrels at 4800-5200 fps and until I Nitrided all but lathe turned bullets were coming apart. Nitrided stopped most bullets from coming apart.

When I went to a 16 twist barrel plus Nitride I have been able to shoot all bullets and No bullets are coming apart.

I have yet to wear out any Nitrided barrels and I figure the 6.5WSM and the 300RUM are well past 1000 rounds and accuracy is intact. Throat shows some wear but I haven't changed bullet seating at all. I see no need to change the seating depth for a really long time.
