Proper way to use it?

[RetiredArmy]

J.B. Paste or Isso, doesn't matter to me. I have read until my head hurts. I'm not asking to use or not to use, what I would like to know from those of you who DO use on a regular basis, will you please detail your methods for me? What is your method and how often used. Please consider this cleaning for dummies(me). All of my rifles except 2 are savage factory that will generally shoot 3/4 Moa or better some times. I do not compete except against close friends, looser buys lunch.
Thank you for your time and effort

great for cleaning carbon out of the throat. parker hale jag with patch wrapped around it soaked in C4, losso paste on the outside. short stroke the throat and about 10" up the bore with a back and forth motion. repeat until the.patch comes out clean. repeat about every 200 or 300 rounds or as needed to keep the carbon in the throat at bay.

Small quantities rubbed into the patch. If it scrapes off on the boreguide thats too much for me. Takes too long to settle out if i use too much

"repeat until the.patch comes out clean."

If IOSSO is used on a stainless steel barrel it will always come out black, whether the barrel is clean or not.

If its not black even on an unfired barrel you aint doin something right

guess i just was in a hurry and didn't explain myself well. after short stroking that throat you want to patch it out very well. Get the abrasive out of the barrel. if those patches don't come out clean then repeat. i use boretech C4 on the patches and the last couple dry.i use a cheap lyman borescope to verify that the throat and bore are truly clean.

When I use JB, I wrap the patch around a stiff nylon bore brush and scrub till the scrubbing is done. When I am done with JB then I spray carb cleaner down the barrel and follow with dry patches to get all the paste out. Then I might follow with a few patches with simichrome on a tight fitting jag if I feel the bore needs fine polishing. Then clean with carb cleaner again.

Iosso- use an Iosso brush of the right diameter. Load the brush with iosso and short stroke the carbon areas. A tight patch on a jag pushed slowly through the bore will tell you where the trouble spots are.

JB-saturate a patch with oil, rub JB into the patch and short stroke the problem areas.

With either one, clean the bore well after.

I've always wondered the same thing, but will tell you when and what I do.

When a bronze brush starts to feel tight near the throat I get out the JB. I spread the JB on a slightly oversized for the caliber bore brush and short stroke it back and forth. I test that with the bronze brush and when the brush goes through the entire barrel with uniform pressure I call it good.

Thanks for all the feedback. Keep them coming. I will start with an older savage 204 ruger. Have no idea how many rounds are down it. Shoots well. Will cut my teeth on it.
Thanks

I hope you have a coated fiberglass rod for that 204. I tried this treatment on mine with a couple of different steel rods and bent them both. The 20 caliber rods just don't take well to the amount of force it sometimes takes to do this kind of cleaning.

I push most of the powder fowling out with a couple of patches lightly coated with Hoppes gun oil. Makes for a nice prelube before you use the JB's. Cuts down on the bent cleaning rods.

I have used Gunslick Foaming Bore Cleaner for years. I use Dewey rods that fit the bore. I cut up old cotton double nap flannel sheets for patches. After letting the foam work over night I push it out with a patch, blue-black slime runs out. Then I use nylon brushes dipped in 5W-30 synthetic motor oil. At first I feel some resistance but then the brushes glide easily. Then after 5-7 brush passes I go back to the patches again, they rapidly turn from black tarry to almost clear after 2-5 passes. I would guess the synthetic motor oil removes carbon. Very rarely and only on certain barrels will I use JB. My barrels are highly lapped and mirror bright inside. When tilting the bore while viewing reflections can be easily seen. I think I can see interference rings but I am probably looking at rifling. Periodically, I wash my nylon brushes in hot soap & water. My stainless barrels are perfectly lapped and no more lapping is needed.

I use Iosso in my rimfires. I was taught to always let the abrasives do the work at work. I strive for that when using Iosso too. In other words, I don't like whatever combination I'm using whether it be a jag or a brush wrapped with a patch to be super tight. Rods won't bend this way.
Again, let the abrasive do its work. Not muscle!

I agree with everything you said, 20's are hard though. There's not much room to work with in there. I resorted to pull through methods for regular cleaning and left the rods for serious cleaning and copper removal. I never found a satisfactory pull through method for cleaning out copper. I never tried wipeout or similar cleaners though, maybe they would have been the answer.

In the end, I sold my 204 Ruger. It just required too much special attention. I decided that it was easier to stick with 40 or 50 grain pills out of my 1/12 twist .223 rifles.

Meangreen, you need to hook up with fyrewall and get some of his "highly lapped and mirror bright" barrels.

 

[urbanrifleman]

Super Slick Stuff for carbon. (you can buy it at Lowes)

Boretech Eliminator for copper. (nothing else is even close)

JB Paste (I like the can better than the tube, and Walt Berger used it)

 

[Alex Wheeler]

I use a nylon brush one size smaller than the bore and wrap a patch around it. Put the iosso on the patch and I put some hoppes 9 or wd40 on there to help the slurry. Stoke the first 8 inches 10-15 times. Then the full length of the barrel a few times. Dont push it out the muzzle. Thats all I have found is needed if you dont let the carbon build up.

Worth the price of admission. Just made my first donation to the sight because of this and all the words of wisdom I have read on this sight. Thanks to everyone, keep them coming.
