Jb use..?

[Rsadams]

When you guys use jb bore paste do you just use a patch or a patch wrapped around a old brush..?

Thanks..

You should only use JB if you want your rifle barrel clean.

That helps

I use isso or JB on a patch on a wore out brush
Or just on a nylon brush either way works about the same

Before I had ever seen a bore scope a new friend told me he had one and we were going to see if I knew how to clean a rifle. I got out my rifle and cleaned it and told him it was CLEAN. He looked and said it is the cleanest 'Ive checked of people that don't have a bore scope, and have never checked their work. He then let me look and I could see the carbon in the corners of the groves of the rifling and gold color near the muzzle. He wrapped a patch around a Parker-Hale jag and but JB on the patch and had me push it through the bore with a stop so as to not let the patch come out of the muzzle and damage the crown. A second look in the borescope showed a perfectly clean barrel. Now I have written a paragraph and if you didn't believe me before, you probably won't now. I am tired of writing paragraphs to internet experts. It was proven to me I didn't believe but I saw with my own eyes. The rifle I cleaned was cleaned before I felt my house and I cleaned it in front of him for the second time and it still wasn't clean. With JB it was. Bring on the flames.

If you don't mind enlarging the bore or rounding off the edges of the rifling, keep doing what you are doing with the JB.

Relax francis. why would he ask about jb if he DIDNT want a clean barrel.

Regner Please forgive, Claus and I have had My 2910 Ford tractor in so many pieces in the last few days most would not have known it was a tractor. I always get like this when I have to work on something designed by a Brit.

 

[normmatzen]

Not designed by a Brit! By a Scot!

I know this guy,,he might just be brushing his teeth ,got ya,joke time

That is ridiculous. Simply ridiculous.

If used in moderation you're correct. But JB is an abrasive and could possibly polish or lap the barrel to an extent if one got after it.

 

[Milo 2.0]

So could a bare patch if you stroked it 10 million times. The abrasive in JB is too mild to cut stainless. It's a hardness thing.

I'm sure, and if your barrel is spotless and you continue and your patches keep coming out gray it's not removing some metal. Witches brew will do the same, it's a talcum powder we pat on our privates on a hot day.

Ya think?

Ask Bartlein Barrels what happens with their guarantee if you use it in one of their barrels. The late Gale McMillan would roll over in his grave if he could hear people bragging about the use of JB or any other abrasive in one or their barrels.

 

[Milo 2.0]

Talc will barely polish auto LACQUER much less steel.

Like I said, it a hardness thing. Quite brilliant really. It has enough abrasive to remove or grab the abrasive soft materials but not enough to cut the steel.

Here's one that was before your time:

You amuse me.

Let's do some math... After barrel break I clean about every fifty rounds. Let's say I have a 6BR. Will say about 300 rounds of usable life (but really the throat only wears out not the bulk of the barrel). That is 60 cleanings. Let's say that is 10 strokes with JB per cleaning. That is 600 strokes.

600 strokes with JB paste is nothing. Do it on the OUTSIDE OF THE BARREL!!! You won't even shine the sanding scratches!!!

You better head back to gunsmithing school, JB is an abrasive and, over time it will remove SS, as in land edges.
A tenth here, a tenth there.
Ask any long term BR shooter about awareness of ruined barrels at the hand of over zealous JB users.

 

[Milo 2.0]

I really don't care. It is still ridiculous.

First of all there is absolutely NO WAY to prove the assertion that JB removes steel to the degree you just stated. And Like I said, I could show you that I could polish my stainless barrel all night with JB and it will not so much as polish a spot. Much less remove material.

Quit while you're still above water.

Do some research and find the articles written by the late Gale McMillan. He proved, via borescope, the removal of material in the bore along with rounding off the crisp edges on the rifling that the barrel makers work so hard to put in place. The hard core SR Benchrest shooters that use it, do so for a few inches into the barrel. They also change those barrels as often as most change socks. It's an abrasive. Toothpaste isn't very abrasive, but it's abrasive enough to clean your teeth, and that enamel is hard. As Gale McMillan stated… "the barrel makers love you".

The link is pretty clear on Gale McMillan's views:

You can also find his statements about the use of JB or other abrasives under "the wisdom of Gale McMillan". He did, of course, know a bit about barrel making
