Iosso - How do you use it??

[PatMiles]

Give it a try! It cut my cleaning time in half.

It's been ordered!

 

[ridgeway]

I wet a patch with 50/50 hoppes/Kriol mix. Squeeze some Iosso on the patch. When I put patch on jag...put iosso side on first. No more mess. The wet lube on patch helps agitate the cleaning action.

make sure to use some oil also down the barrel and on the brush when using isso or JB

I think the oil instructions explain their process with the iosso paste.

Thanks for all of you input guy!! I will order some ThorroClean, Iosso, Brushes and Felt Pellets tonight. I truly appreciate all of your help.

Be real careful using any abrasive cleaner on a brush.

"The gouges are from the brush going up and over the tops of the lands and trying to rotate with the twist of the rifling."
This man probably forgot more about barrels than I ever knew. So I guess there is a reason Bartlein doesn't want abrasives used in their barrels.
Have I ever used abrasives, yes I have, sometimes they are necessary, but not on a brush and not on a regular basis. I use them real sparingly, I go real slow a little at a time and I borescope to make sure they are having the effect I want.

I've seen this picture a couple times.

I've used Iosso and JB a lot in many, many barrels with worn bronze brushes wrapped with a patch. I have never seen any marks like that.
I would love to know what it takes to make them.

As I recall, that was traced to a brush whose handle bearing wasn't up to snuff, wasn't it? Had nothing to do with abrasives, if I remember right (haven't re-read the thread.)

I think the oil instructions explain their process with the iosso paste.

From Iosso's description of the oil (excerpt):
"For Bore cleaning, apply the solution to a patch, run it through the bore several times. Next apply Iosso Bore Cleaner sparingly to an Eliminator Brush. Run through the bore one or more times and follow with clean, dry patches until one comes clean. Lastly, moisten a patch with solution and run through the bore. Follow with a clean dry patch."

What does putting Iosso paste (Iosso Bore Cleaner) on a brush do? Is there enough surface area from the bristles to allow the paste to do anything? How much of the paste is wasted seeping down between the bristles?

Not slamming anybody; genuinely curious. It just doesn't sound all that effective to me.

I do not doubt the damage shown in picture post #26.

Not willing to do a locked up brush/rod push and pull routine, I opted for a rotational brushing approach. I have a pulled M700 stainless barrel in 7mm-08 with 6200 shots fired. Into my vise it goes. I used a new .30 cal. stiff bristle nylon cleaning brush, with .017 dia. bristles and unknown brand. It was spun in a drill at a fixed location near the muzzle.

Photo #007 is before any brushing action.

First it was spun at medium rate RPM for 15 seconds in a dry, no abrasive used condition. That nylon alone did some metal removal as seen in photo #008 and bore outside the mirror view.

Next, some JB compound was applied to the brush. A couple of drops of light gun oil was also applied to help sling the compound outwards during rotation. Just 30 seconds at medium rotation speed. Now we are cutting some steel. Pictures #009 through #014.

I could easily feel the tight cleaning patch moving with less resistance in this zone from missing metal.

.......the brush diameter was reduced by .020.

Same here => I use a patch wrapped around the brush. But, I think I prefer the approach of folding over an edge of the patch to get it a tight fit.

I do not doubt the damage shown in picture post #26 at all.

Not willing to do a locked up brush/rod push and pull routine, I opted for a rotational brushing approach. I have a pulled M700 stainless barrel in 7mm-08 with 6200 shots fired. Into my vise it goes. I used a new .30 cal. stiff bristle nylon cleaning brush, with .017 dia. bristles and unknown brand. It was spun in a drill at a fixed location near the muzzle.

I could easily feel the tight cleaning patch moving freely in this zone from missing metal.

.......the brush diameter was reduced by .020.

What's your net of this?

 

[bobm]

.....part 2..... same extreme process using a new .30 cal. Pro Shot bronze brush. The stiff springy bristles measure at .005 dia. I JB'd half of the brush, left the thread side bare for a two point condition view. I went deeper in the bore and spun the brush at medium RPM a full 30 seconds. I ran a cleaning patch through and then back for a Teslong view.

#15 is the bare brush section result......#16 is the JB'd section result.....#17 shows original bore condition to JB'd brushed condition transition line.

The new .30 cal. brush lost .040 of it's starting diameter.

What's your net of this?

This little experiment just proves to me how abrasive in nature nylon bore brushes are. Even more so when the bristles are wiping abrasive compounds between them and barrel steel. They have no business being used on premium match grade rifle barrels in any fashion. Just my opinion.

Hell, I wouldn't use them on my factory hunting guns.

 

[jelenko]

And, bronze brushes?

 

[bobm]

And, bronze brushes?

Well, this was just a extreme demonstration between these two materials. My goal was to inflict damage to the steel with common bore cleaning items. Clearly, the bronze brush had no visible negative effect on the lands or grooves of the softer stainless steel.

Use your nylon bore brushes for neck preparation on brass cases, not cleaning bores.

Use quality bronze bore brushes properly when cleaning rifles. (back and forth)

I'm not entirely sold on a brush and abrasive causing the damage shown in photo in post #26

 

[bobm]

....part 3.....same process using a chrome moly barrel. A 3200 shot pulled .260 was selected. There was enough material left on the previous brushes to do a reduced bore size test. The 30 second rotation time did not produce much damage evidence, so a full minute of rotation was used.

Photo #18 was bore condition before scrubbing.....no dry bronze test done.....#19 is bronze brush using JB, for one minute of rotation. .....#20 is nylon brush dry for one minute of rotation......#21 is nylon brush with JB for one minute of rotation.

The nylon brush lost .015 from it's starting diameter, the bronze .020. Both brushes now scrapped. Conclusion: CM is tougher than SS.

Abrasion test over.

Questions will be answered in the order they were received.

 

[jelenko]

CM is tougher than SS

Very cool!

 

[fatelvis]

After hearing repeatedly, and seeing proof for myself that CM is tougher than Stainless, I'm seriously thinking of choosing CM for my next barrel changes.

 

[jelenko]

Yeah. I'm at the same place.
I just gotta get through the 4 stainless steel ones first.
