IOSSO bore paste

[StraightPipes]

Iosso might solve a carbon problem for me....

Cant get an answer to this question; Talked to Iosso direct, this paste has "no abrasive" in the mix. Talked to Brownells, they say it "has abrasive" in the mix.

If it has abrasive in it, it would be good to know.

sorta has abrasive I was told it was ground gypsum, so nothing like what aluminum oxide or silica sand would be.
It does work good and only one patch short stroked in the first few inches of barrel and then pushed all the way out usually does it removing 90%.

Hello Jim;

Thanks for the info. Here is my plan.
The Sinclair catalog 2012-B, on page 138 you will see these new "SUPER BRUSH BORE TIPS"..#100-010-573SE.

Im going to attack the throat with one of these "MOPS" if you will. Some IOSSO paste and "LOW" rpm.

SEE, Im going to break out of this problem we all have in this area. I know what you do Jim, so what do you think of this approach? Shooters have tried it all, from diggin at it to hammering and just about every caustic brew you can think of.

I think these "SPONGES"and the IOSSO may work. The sponge should conform without over doing it, and the paste should be gentle enough(if turned slowly)so not to leave any tracks behind.(a brush will)..

I will borescope as I move along...

Anyone, feel free to jump on this.. Good, bad or?

I turn it by hand so I think if you turn it slowly it should work and borescope often.

check page 10 under "diy carbon ring scraper" This may help you.

Applying Iosso is not rocket science.......a simple cotton patch wrapped on a jag has worked just fine........ 1.5 cents vs. $5 for a "sponge"?.....I have high regard for Sinclair Intl......but sometimes their niche tools and accessories are a product looking for legit usefullness. And I don't see the need for a sponge to replace a patch or mop.

 

[StraightPipes]

Rocket science, no!! Having an active sense of adventure, yes.. Patches dont cover any ground when you turn them. Far as spinning metal objects in my chamber, not me.

Put a little iosso on a patch and wrap it around a worn out brush. That covers the bore.

To get rid of the carbon ring, put the iosso on an oversize brush and use a turning motion. Check it with the bore scope to see when to stop. I use a really slow electric screwdriver to power it.

FWIW,

The only "spinning" in my Iosso regime is the patch engraving in the rifling as i short-stroke the throat area and push the patch out the muzzle........all done with a Lucas bore guide in place. This is a proven procedure that controls carbon build-up.

I think Iosso paste is a great product. I have a bore scope so I can evaluate the before & after use results and effectiveness for my cleaning regimen.

For the dreaded & inevitable carbon ring, I first confirm that the carbon ring is there with my bore scope after a routine cleaning. I use a bore brush 1 bore size larger than my bore (example for a carbon ring in a 6mm barrel, use a 6.5mm brush). I dab an amount of Iosso the size of a green pea on the first 1/4" or so of the 6.5mm brush tip and carefully distribute the Iosso 360 degrees around the brush tip. Then screw the brush into a non-rotating short Dewey chamber rod. I carefully insert the brush until I just feel it engage the rifling and then back it out so that I know I'm in the area just ahead of end of the neck. I hold the rod centered with with my finger tips, at the rear of the action & twist the rod with my free hand. I count 50 or so revolutions, carefully keeping the brush as centered as possible and not allowing it to work forward. Then clean again as usual, to remove the Iosso.

This usually works for me, as I have the luxury of a bore scope and I don't allow carbon rings to get too large. This carbon ring removal process using Iosso is described in detail in Tony's book.

Tony also describes an effective way for removal of stubborn carbon and/or copper in the barrel.

I have found Iosso to be safe & effective for carbon & copper removal and doesn't damage the barrel or shorten its effective life. However, bad cleaning technique can & does. A good bore guide bore is a necessity and a bore scope really helps.

LHSMITH, sorry to send you "spinning"!!!! LOL

I thank all of you for the advice. You see, it was the "new" idea since Sinclair put out these sponge tips that peaked my interest. Ive tried all of the customary procedures for many years.

If this new approach works, I will post the results. I will post if it does not also.

+1 on the process Larry described.

Sorry for asking this, I know it doesn't really pertain to the main question but I was curious at what point will a good quality custom barrel have this sort of carbon build up. Does it get worse if you fire a gun hot, or does it make a diffirence.

Again my apologies for hijacking, I just thought I could get a quick answer.

IMO,

the type and brand of powder should be the real problem. Trimming the neck too short will probably determine how large the ring becomes.
