Discussion in 'Gear Talk: What to Buy? and Gear Evaluations' started by Raythemanroe, May 7, 2015.
I was wondering how many people use IOSSO and how does it work for you?
Withut it and C-4, you almost cannot shoot a Dasher.
It takes out carbon in addition to all the other foulants. J.B. is not close.
It's a paste right? Is it hard to remove?
I use the same combo as the first poster. Three or four patches wet with C-4, 3 for 4 dry patches. The paste is used just in the throat area for me; then followed by C-4 and Kroil; again.
Great stuff, Does anyone know the correct pronunciation?
How long can you leave it in your barrel?
Since it cleans by mechanical action rather than chemical, I do not believe that there is any advantage to letting it sit in a bore. I use it, but sparingly, and with considerable care. It is the go to product for hard carbon removal.
I should clarify. There are a lot of discussions on the internet in which the word carbon is used, and from reading the posts including the methods used to remove what they seem to be discussing, the authors are in fact talking about simple powder fouling. To my knowledge true hard carbon is not removed by solvents and or brushes but rather requires an abrasive. There has been some discussion in the past about the claim that IOSSO not being an abrasive. Let me say this. It cleans the barrel by particulate action, whether you want to call it an abrasive or not is up to you, but it is in the class with JB and Remclean, and acts in a similar fashion, although the particles in each of these products are different, as are their results. To me, IOSSO seems to have finer, sharper particles than JB. I have not used Remclean, but what I have read has not encouraged me to do so.
When you pick someone to listen to about bore cleaning, it seems to me that it would be better if they had, or had access to a bore scope. Anything else is just guessing.
+1 to what BoydAllen said My bope scope has either confirmed my worst fears or allowed me to go to sleep at night knowing all is well more time than I can ever count. And thats not on my rifles only but also my friends and if I'm inspecting one for some unrelated reason. If you feel like I just high-jacked the thread, my apologies. My intentions were to say that I use J-B every 250 to 500 rounds, and am very methodical as to how I use it. While we are one the topic, has anyone ever used Flitz? If so, what are your thoughts, recommendations etc.?
So would you guys say Iosso is more or less "harsh" for lack of a better term, than JB's?
I just rubbed Iosso & JB between my fingers, Iosso has more of a ''harsh'' feel to it. I use it when carbon shows up, with NO worries on what it does to a barrel, we are talking about Stainless Steel right?
Worry. That is why we are careful when we use it, and use it only as much and as often as is needed. There is also the issue of polishing. IOSSO will polish a bore, and an over polished barrel , especially in the front half, will cause jacket fouling problems. Barrel makers who lap are very aware of this, and as a result put a final finishing lap on barrels that is fairly coarse. You might be surprised what grit it takes to reproduce a similar finish. So called hard carbon is so hard and well adhered to the bore that an abrasive that is effective in removing it has to have the potential for damaging a barrel if used sloppily, and too frequently. Don't assume anything. Sloppy cleaning rod technique and cheap bore guides are epidemic. Once, sometime after I had shown a friend how I use IOSSO, and we had looked at his barrel before and after using IOSSO, I asked him how his barrel cleaning and accuracy were coming along. He told me that he really got busy with the IOSSO the last time that he had cleaned. This was not good to hear. Evidently my instructions had been forgotten. I had told him to be careful, do it a certain way, and to be sparing in the number of strokes.
Boyd my gunsmith and very good friend of mine uses JB when he is done with his relay and the shoot off! And he is one of the top shooters at Williamsport. I believe he has won more World Opens the anyone I know. I've heard him mention using IOSSO before, but don't know if he still does I'll have to ask. I always thought he used a lot of elbow grease, but you can't argue with success. OH and he uses it on a soft brush. Gave him some on his Birthday last week.
I use J-B NON-EMBEDDING COMPOUND without issue. I also use Tubb's FF/TMS.
Have ISSO on hand but haven't tried it as my system is working well.
Flitz was mentioned and I can say I ruined an excellent barrel once with Flitz. That is, it removed carbon alright, but the bore went from pretty much nothing for copper fouling to a bad copper fouler in one move(a bad one). I could not recover from this, even with application of J-B & Tubb's.
A friend made the same mistake with J-B bore bright. Ruined his barrel immediately. Maybe he got a little overzealous with it, I don't know, but I figure he polished his bore like I had -with Flitz.
We do NOT want to polish our bores. The best barrels do not come polished. They're lapped to just the right surface profile.
When was his Birthday? Mine was on he 7th
What I like about IOSSO over JB is, while I find they both will yield similar results, I find it takes about half the work (passes) to remove harder layered fouling with IOSSO. And find it to be one of the best ways for removing carbon layer.
In my cleaning procedure I use it after I have the bulk out, and use it every time I clean (as many others do as well).
While it is good to be careful, restrictive, and sparing with many cleaners, I personally find some of the input to IOSSO over zealous and bios. For I myself see the good in IOSSO, and the advantages to using it over not using it (especially on carbon layer and for carbon prevention of the chamber-end, lead and throat).
I do strongly suggest to read and fallow the instructions that come with IOSSO, just as one should with all bore-cleaners.
IOSSO is a great bore-cleaner.
I use IOSSO and like it. The point that I was trying to make is that some care is required, this because there seems to be a lot of "if some is good, more must be better" out there, along with ineffective bore guides and bad rod technique.
The way that I use it was described years back by Tony Boyer, who used it a lot more than I need to because (I think) of the powder that he was shooting at the time, T. I use the softer black nylon brushes and fill them to the ends of their bristles with IOSSO. I short stroke the brush in the throat and back foot or so of the barrel, and then in one motion out the muzzle, where I remove it, the only time that I take off a brush at the muzzle. I follow this with enough wet patches to remove it completely. I do all of this after a regular cleaning. The bore scope tells me how often I need to use IOSSO. 133 does not seem to form anything that patches, a bronze brush, and Butch's can't remove. With the LT powders, I use IOSSO from time to time, but certainly not every cleaning, and any time that I use an abrasive, I expect to have to shoot more fouling shots than normal to settle the barrel down.
Once I used FLITZ in a barrel and was alarmed to see how quickly it polished. Luckily I had looked with a borescope soon enough that I did not ruin the barrel by over polishing it.
As for JB, I tend to use it when less extreme measures are required. I put a little oil on a patch and a dab of JB, rubbing the patch between thumb and finger to work it into the weave. I normally use a smaller jag for solvent, but for JB work I may switch to one that is the correct size for the bore that I am cleaning...depending on the fit, or I may use a Parker Hale style of jag.
We must have went to the same school of thought. I let the barrel tell me when it is time fore some "paste". I concentrate on the throat and about 4-6" forward. Then in one smooth stroke push it out the muzzle. A couple of wet patches of Break Kleen, then a dry and out comes the bore scope. This method has never failed me, so if it isn't broken, lets not fix it. My question about Flitz and now Iosso is are they more or less abrasive than the tan colored J-B?
I've polished my bore with flitz but when I'm done I clean it with Kroil till its all out. But maybe every 300 rounds or so. Maybe if you left some in the bore and shoot it you may ruin the barrel, So tell me how a highly polished barrel is not good?
Ray his Birthday was May 2nd, Mine was Yesterday. But Happy birthday to you also. Sorry I'm out of brushes.
Bores that are too rough, or too smooth, copper up more.
Ruined, for me, is any bore that copper fouls out to let me down.
And while I believe carbon is the ultimate killer of bores, there is no good reason bring on a bunch of copper fouling. So I try to manage carbon while keeping similar surface profile to that of a well lapped bore.
Sounds like IOSSO does this.
If a high polish was 'good' for anything, your best barrels would come this way (they don't).
Mikecr Sorry but never have a copper problem with mine, before I ever fire a shot through mine I JB & flitz mine to get any machine marks the reamer has left. Then there cleaned with Kriol before a single round goes down them And they clean up very quickly. I have two new ones I'm working on now.
Let you know how it works on them!
