does anyone here use colodial graphite for barrel prep?

[ogre6br]

I dont really know much about it but it is supposed to be good for running in barrels even if you dont shoot moly projectiles.

what do you guys think about it?

can it be obtained here in AU??

thanks

See you got a reply to this on the Saubier forum .
I'm using Tetra Gun which is a PTFE product that's supposed to do the same thing , seems a little easier to apply and can be used for other things . No nasty black mess . Makes the bolt run smoother than any oil based product that I've tried .

Ogre,

I have a 'thing' about graphite, you may have seen the topic on the AHN forum awhile back. It is a form of pure carbon....and yes I know it is used as a lubricant.......BUT it is not designed to be used under the extreme heat and pressure found in a rifle barrell....unlike moly which is engineered to operate in that environment.

As for running in a tube with it, maybe it is behaving exactly the way you want it to, by being abrasive and wearing the rough spots off I presume by coloidal they mean 'graphite particles suspended in oil'. So I would only pass a patch through with a spot on it.

Running in with molly pills is possible but takes a lot longer in my experience, I guess the pills are just slipping over the rough spots rather than tearing them off. It's usually when I fireform my cases too so they are reduced loads. I much prefer the 'old school' bare bullet method.

Kenny I was just using the term/name for the stuff that I had read on several US varminting boards.

Greg Tannel a G-smith of renown with the small caliber guys swears by it and he has converted a lot who use him as a smith.
and they say good things about his work.
He's allways written up well in SCN

I really have NFI about the stuff thats why I was asking.

I will be using Lothar Walther barrels when I have some $$ to get some things done- I dont expect them to have rough spots.
I dont know whether it's worth treating the barrels with this stuff or not

I must have missed your post/topic on AHN about it. link please.

When I get my project rifles built I want to buy once cry once and do it right first time and get good long life out of these barrels-
Will this stuff give me longer barrel life--- NFI-- but if it will I'm prepared to try it

thats also why I'm asking all the questions as I dont have a fall back position if I screw these ones up.

thanks

It is pointless to 'run in' a barrel using a friction reducing compound. How's it going to run in? I run in all my best barrels with bare bullets and then switch to moly coated after 100 rounds. Many years ago I bought a brand new Torana GTR XU-1 and it stated in the book that friction modified oils should not be used for at least 10,000 miles. It was at the same time that Castrol GTX came on the market.

Jimbo,

That's the way I do my barrels as well, but when they stop copper fouling is when I switch to moly. Normally no more then 50 rounds.

Ogre,

Yep it is a hard one ........

I would not bother personally and just use the old school method, at least that way I KNOW I won't ruin my new tube

I take a lot of what's on the web with a grain of salt unless I can see some sense in it. And I can't see how it would be of any benefit.

I can't find that link either, it was more about case lube, anyway......my opinion was not recieved too well Do a search on graphite's properties and you will understand what I was talking about
