Nitride the barrel

[macds]

LOL

Thanks Earl, and Merry Christmas to all :)

we use mmi-trutech out of arkansas to do a meloite coating its not cheap but quality is awesome

My favorite option is to do bolt and action with the bearing/spring_ It is as smooth on one could possibly want it.

Neal


When you say bolt, do you mean the whole bolt to include all baffles and bolthead minus the springs? Just wondering how far you've taken to the bolt to.

Thanks,

Kevin


this is how i sent mine in..

Thank you!

Thanks rsb and mscott!
Mscott- AWESOME rig, really. very good job, I am a Choate Tactical fan and the whole
rifle turned out cool as ****. Those numbers spell potent mojo too.
The barrel coming from Sinman is for a .338 Edge project that I am using a Choate for
also, some pix in picture post, if it turns out close to that good I will be happy.
with what I have heard so far, its gonna be break in, find an accuracy load, then
off with the tube & send to Nitride.
I hear those stocks are heavy. Is that right?

Got off the phone with Chris from Benchmark today. It costs $160 to do a complete action, and that includes sandblasting and cleanup as well. Not a bad deal considering what you're getting!

So what's the general consensus when it comes to breaking in the barrel prior to sending it off to be nitrided? I think I've seen it go both ways so far.

Im really really tempted to send in my first action to get done. I know bobby from freedom gunworks had quoted me before at $100 for the action and $25 for the bolt. I wouldnt be surprised if that went up by now.

Does anyone have the price for H&M to do a complete action or just the barrel? I may just do an action for now and do the barrel at a later date.

Brian

[Ring31]

H&M will do the barrel, bolt, bolt handle, action and even the trigger if you want for 200, call shade up and talk with him, tell him Russ sent you..

[airaddict]

I think im gonna hold off on the barrel for now but i do want the complete action done. Do u have a contact number or is any number on their website ok to contact shade at?

Brian

[Ring31]

just call the main # and ask for him... il be taking 5 or 6 guns in, in a few weeks to get done, including a entire LRPV in Tan..

[airaddict]

Tan? I thought the only color was a blackish blue depending on if its polished or left a normal matte?.

Whats the typical turn around time?

If you have SS part "this can ONLY be done on SS", H&M can do this..
"Tan" Nitide.. same corrosion resistance and same lubricity as black... but not as hard.
Normal barrel SS is 35 to 45RC stock, black will get it to 70RC, the tan is in the 50's

1 of a kind.... just had a rifle "tan" nitrided..

only 1 company does this, and they have done pistols in the past, this was the 1st full rifle they have done, they are the OEM nitrider/melonite for S&W, Spikes, KRISS, Robinson and a few others...

This from a barrel manufacturer: Nitriding will not help with throat erosion. Now the rifling in the barrel will last longer but here is the rub....that doesn't matter as after nitriding the rifling and throat are at 70 Rockwell and your reamer won't do that....ever, so you can't re-chamber a nitrided barrel; nor can you "sink" the reamer in and "freshen the chamber". There is no valid reason to do this to the interior of the barrel. Actually you are shooting yourself in the foot. And having a "fresh" barrel nitrided will extend the break-in period.

I will have my action and bolt and, most certainly, the outside of my barrel done. Money very well spent there.

Please don't get all up in my face over this as it is what a qualified source told me. If you disagree, by all means, please share the issues with me and everybody.

tests disagree with that..

If you wanna shoot yourself in the foot ask a "barrel manufacturer" to recommend a treatment that will prolong barrel life. Honestly do you think anyone is going to tell you to do something that will hurt their sales? You really need to consider the source and get some facts. He may really believe what he is saying but is that because he hasn't looked, hasn't tested and just doesn't want to know? Shouldn't be so hard to determine if this does or does not work. So far all you have is a few facts about what the treatment does to the metal and that it can't be machined later thrown in with a guess that it doesn't help control throat erosion. Not to mention all the down sides mentioned should not be relevant if barrel life is extended. A lot of testing apparently shows this may help extend barrel life. Opinions are great and some are backed by a lot of experience but there are a lot of these treated barrels in the field and shooters reporting extended life. Before you make a choice and comment to others on the subject get a little more information. I'd love to see some testing that supports the barrel makers opinion if you have any. I've seen enough positive data from multiple sources to not discount the idea based on one source. Can you provide any support of the comments that you have reported? Who is this "qualified" masked man? ;D

Thank you Ring.

I will add that I am at 2.5 times the barrel life after Nitriding my 6.5 WSM barrels compared to none Nitrided barrel in the same caliber. I have a friend at roughly the same round count with the same caliber and both barrels are begining to show throat erosion. However the average round count on a none nitrided barrel years ago when the world began wildcatting the 6.5 WSM was averaging 400 rounds. I am just under 1000 rounds.
