    Barrel Cleaning

    Dennis, there are guys with loads of experience that I hope will chime in for you.

    To some degree I think it depends on the barrel and type of rifling. Some may need cleaning more than others.

    For me, I clean my barrel when competing after each card. Sort of, whether it needs it or not.

    I can't remember the name of the product I use. I believe it may be called "Crown Saver".

    It's basically a thick nylon cord with a loop on the end of it for the patch. You push that through the barrel from crown to breech. You use a straw to get it started into the barrel. Then add a couple of drops of your barrel cleaner/lead solvent of choice to the patch and pull it through the barrel from breech to crown. The nylon cord has a pull handle on the opposite end of the loop.

    That's really it. At least as far as what I do.

    Youíve been on airgunnation!, ya me too, if itís about JB BORE PASTE???, I havenít found the need, if it will harm a barrel?, if you were to talk to 10 different airgun or centerfire smiths probably get 10 differing answers!, all I know is I used it in my center fire guns to help with carbon in my ppc & Br comp. guns I used it sparingly, was under the impression it could end up lapping a barrel if not careful?, I would not use in my 12 groove LW thatís for sure, Iím generally lazy and one of the attractions of airguns is not as much maintenance, cleaning etc., Iíve always kept on top of it (cleaning ) I suppose if a barrel went south for no reason I might give a much more aggressive procedure (JB bronze brush etc. to try to bring it back!) I am sure ther are much more experienced shooters who will chime in and I hope they do! Cause I think We could all learn from their experience...

    Dennis:

    You are going to hear many different answers, there is nothing written about cleaning a barrel...It all depends on the barrel, cleanliness of the ammo, hardness of the lead used in the ammo, velocity that you are shooting, etc...In my opinion you have to find out what works best for your specific barrel...If you ask me what I use, it is very simple: One wet patch of either Kroil Oil or WD-40 (both are penetrating oils) and then 2-3 dry patches followed by shooting 4-5 scrap pellets for seasoning the barrel before starting a new target...I do this routine after every card when competing and about every 2 cards when practicing...Now, I am talking about .177 calibers shot at a max velocity of 815 fps (I shoot LV at 797 fps. with 8.4's or 715 with 10.3's and HV at 815 fps. with 13.4's ).

    I've found that for my particular use I don't need lead solvents nor frequent polishing....I actually clean any new barrel thoroughly, then polish it with Flitz or similar fine polishing compound and never polish them again and I have barrels with well over 50-60,000 pellets that are very precise...I use a borescope if the barrel loses accuracy and I suspect leading, but this has never happened in a BR barrel at the velocities I am talking about; it does however when you pass the 950 ft. barrier and it gets worse when you play around 1,100 - 1,200 ...Specially if you are shooting .22's or any of the larger calibers. Big bores at high velocities lead your barrel like butter on a piece of bread and you need to clean them following the routine used for removing lead from black powder guns.

    I forgot an important issue: Many people believe that if the patch comes our grey that the gun is leaded or still needs cleaning...Nothing farther from the truth...ALL metals oxidize in contact with air forming a very thin layer of oxide immediately after cleaning/passing a patch...A dry patch may come out white but then if you add solvent, penetrating oil, Flitz, JB or ..... the patch once again comes out dark...This is why we use one wet followed by usually two dry patches, once a dry comes out clean the bore is considered clean and good for BR precision most of the times...

    For people still wondering, do an experiment : Get a piece of scrap steel and sand it with 400 -800 grit sand paper until the surface is very shinny...Now you are sure the surface is as clean as it is needed to be inside a clean barrel....Then use a white rag with Flitz or any polishing compound and rub it...The rag will come out grey or dark in color all day long no matter how many pounds of polishing compound you use...The more you wait between polishing passes the darker the patch will come out (more oxidation). If you have ever buffed silverware you will understand what I am saying.

    Thanks AZ, I was hoping someone with your knowledge & experience would help out!, what you have described is basically what Iíve been doing(three LW BARRELS 1 standard 2-Poly) never used Kroil, have in center fire barrels, I use some penetrate from boeing on my airgun barrels but have access to both from my work. Thanks, Joe

    You are on the right track Joe...Keep on doing what you are doing...

    Back in the early 60's my dad gave me my first "High Power Gun"...A 3/4 to 1" at 100 yards. .270 Pre-64 Winchester...Cleaning its barrel the patches will come out green, indicating cooper fouling....I used all and every cooper remover I found and completely finished the job after using Ammonia...I went back to the range with with my favorite loads (Dad used to load them for me as I was a kid) and to my surprise, the gun shoot terrible!...Then after maybe 2 boxes of shells the precision started to come back but I discovered that the barrel was fouling again....As a kid I didn't understand how could a fouled barrel shoot better than a clean barrel....Very fortunately my father who was not an expert but a MD was a very close friend to Ed Shilen and Ed asked me to bring the gun. He used a bore scope and air gauged this barrel and explained my father and I that the fouling was actually HELPING its accuracy because of filling in the barrel's pores & imperfections...

    Our pellet gun barrels have pores natural to any metal and also derived from machining...These porous surfaces get filled with lead and this is a good thing as long as we don't get it layered or in excessive quantities....
    Have you ever heard of people saying that their barrels shot better overtime? ...Well, this is why that happens, the lead fills the pores and the barrel becomes smooth enough for good precision....It is not that barrels shoot better because of WEARING OUT of opening up dimensions as many people believe....

    When cleaning a barrel with a wet patch, INSPECT the patch visually and you will see lead particles (dust)...That is all you need to remove when cleaning...Then inspect your first dry patch and you will maybe see a few particles of dust or maybe not, this is an indication that the barrel is getting clean...Once you pass a second or third dry patch all you will get is maybe a little grayish color but no particles...YOUR BARREL IS THEN CLEAN and ready to shoot.

    I've been in competitions where I use dry patches only...The first-second patches come out with dust particles but then the 3rd patch comes out clean...I do this on a Ratchet barrel that Ed Shilen made for testing currently on a Steyr LG-110 that I use in LV and FT (LV Class)...I know this barrel doesn't need wet patches in between targets, but I do clean it with a wet patch after the competition is over (100 + shots)....Sometimes I do the same for my HV gun. The advantage here is that I don't need to "season" the barrel, it is ready to shoot and compete after the last patch.
