I use almost the same "procedure", including IOSSO paste and Carb-out (no CLR though, don't need it). I put procedure in parenthesis because I adjust what I'm doing as needed. If IOSSO doesn't get it the first time I usually wrap a patch around a brush and put IOSSO paste on the patch if the borescope finds something. I'm going to cut back to one IOSSO cycle and soak with carb out. I'm also going to add the triple action oil step. The borescope, this channel, and the forum were game changers for me. I don't shoot competitively but I like the resulting small groups and the simpler loading and cleaning procedures that are discussed in all three places.

Hello. First time watching you or your video(s). Good "Show and Tell" type explanation & instruction. What I do not understand is why you do not use a wire bristle bore brush to clean out the carbon? It is your You Tube channel and your rifles so you can do what you want to. Cloth patches should be used after some passes with the bore brush. Cloth patches and liquid cleaner could take a very long time. In the USMC and later in the Army we used wire bristle bore brushes, liquid bore / chamber cleaner, and then cloth patches. We shot many more rounds than single-shot Benchrest shooters do.

I've tried several bore cleaning products and they all came up short. Recently I used Montana Extreme products, their Copper Killer and their Bore Solvent. I was so hopeful that these would work perfectly, especially since it contains Ammonia which is supposed to dissolve copper. It wasn't to be of course. I've let them sit in the barrel for over 2 hours and still it didn't do any better than anything else. I was very disappointed. I can't return it so I'll just use it up and find something else. Kroil + JB is the only thing I've found that will TRULY clean out a bore. I would just rather have a chemical process as opposed to a mechanical one, but Kroil + JB is the best I've found so far. 30 to 50 strokes is all that's needed, and I don't have to let things soak for mins or hours.

I've commented on this before, so I'll do it again; CLR does NOT ruin bores, ESPECIALLY stainless; I used to MAKE phosphoric acid amongst others at a plant, trust me. Phos acid WAS the primary acid in most cleaners that remove rust and other grime. I've called CLR a few months ago and they told me they quit using phos acid in the calcium, lime and rust remover 13 years ago. (NOT CLR. CLR is NOW the COMPANY name, NOT the chemical inside the containers. if you want the chemical that actually removes calcium lime AND rust you have to buy the container MARKED calcium lime and rust remover, not just any old clr bottle) The acid they now use in the calcium lime and rust remover is a natural acid (the actual name escapes me) that is really mild and wont hurt SHIT. A lot of people don't realize that the actual acid was taken out of CLR a long time ago. ALTHOUGH, even IF they STILL RETAINED the phosphoric acid in there, at the concentration that it came in, it STILL wouldn't have ruined your barrels lol. Guys, these barrel makers are probably assuming there's still phosphoric acid in CLR, and I'm assuming that's why they say it's bad for your bores. Trust me, I use it CONSTANTLY for cleaning parts in my garage, and it is NOT harmful lol. There's no way it's harming your bore.

It for cosmetic reasons, it will eat away the bluing or other types of coatings. Thats why its only used on stainless, its phosphoric acid with detergents.

[@billclifton8400]

Looks like that might be the blue iosso brush but can I ask what jag you prefer to use?

[@wulfie6899]

We need to fund a study using a lab to see if CLR hurts the stainless barrels. Also run a test on iosso paste and oil to see if any damage occurs …..these are the only products tha remove baked on carbon “EASILY”.I think you do more damage running brushes through over and over and over to scape off baked carbon with weak products

[@ErikCortina]

Great suggestion!

[@zgennaro]

Anybody notice if you use boretech c4 at very low round count the barrels cleans up very easily? Like less than 100 shots before cleanings.

[@gracewthomas]

I have been testing Kroil oil for cleaning , thoughts I have good results !

[@William_Charles_Baker]

I've been using Kroil for over 40 years. Works great even on stubborn black powder residue.

[@MrCreateNothing]

Black powder residue is pretty much water-soluble.@@William_Charles_Baker

[@mlone7]

I wonder what carburetor carb cleaner would do? I spray that stuff on carbs, injectors and even EGR valves. It takes the carbon and gunk off of all that stuff.

[@xephael3485]

0:57 you're going to say what's CLR??? Problem solved 😂

[@JJD-9403]

EXACTLY

[@remoman]

'Excuse me, the barrel you send me is bent'.... 'DID YOU USE CLR?'?

[@GlenKimpton]

Because of this video I'm now swapping to CLR.

[@PassionforRifles]

Did you get the carbon easier out with the CLR?

[@greasydot]

I mix up sometging similar to eds red and use a synthetic injector cleaner thatbworks really well on stubborn carbon. If it dont eat injector tips or aluminum heads it damn sure wont hurt a gun barrel.

[@caseysetsodi1990]

So no CLR, what about Free All? I use it and it incredibly effective on carbon, loosens it up and get a bunch out on first patch.

[@rksando1]

Can any of you recommend a borescope that will fit inside a .177 barrel?

[@coyotiess]

Thanks!

[@ErikCortina]

No problem!

[@johnnyi2121]

sir...? What is this "warranty" you speak of? is there a year or number of rounds warranty? Details please

[@tymarkham3931]

Great video brother, where could I pick that bore scope up at? Thanks

[@hank3152]

Look up Teslong, they make several models and are available at most online reloading retailers and even Amazon

[@tymarkham3931]

@hank3152 I was looking, and I couldn't find the foldable one like you have in the video. Do you have a link to that specific bore scope?

[@tymarkham3931]

​@hank3152 I found it, thanks, buddy

[@170boone]

I still have lots of the old Barnes Copper remover. CLR CANT be harsher than Barnes?? Been using it 25 years and no issues.

[@huntmulies39]

Yes CLR destroys metal I left a reloading die ina bucket for several days after my 3 year old picked up off the reloading bench and left it out side for the sprinklers to rust it. It was a cheap rcbs die and it dissolved all the “stainless coating off of it”. After that I stoped using it in my guns for fear of maybe getting some in a thread or something like that.

[@mauricen9926]

What about diesel upper engine cleaner? Used to decarb and works a treat on far more precision equipment than a barrel?
