    Just wanted to run a question on bore cleaning by this fine panel of experts.

    To start with, several of the shooters at the range had been telling me that they only cleaned their bores after 150 to 200 rounds. Some of those being normally quite reliable in their knowledge.

    I have always been sort of keep it clean oriented--not a clean freak--but not let it get real dirty.

    Anyway, I decided to try what they were telling me and all went well for a while. I am supposing that I had approached 100 rounds through my M700 Mil Spec 5R .300 WM when all of a sudden it quit shooting those tight groups. I have been making loads with different bullets, powders etc. to find the most accurate load for the rifle for hunting purposes.
    I was getting some very good 100 yard groups with the Berger 168 gr. Hunting VLDs and H 1000 in the range of 1/2 MOA then the groups got bigger and bigger and it wouldn't group the Accubonds hardly at all. I sat and thought here I am burning up expensive powder, primers and shooting these costly bullets and all has been wasted.
    My sons M700 .30-06 was also giving a problem earlier of similar nature and I got to work cleaning it and thought I would never get all the copper out, but now it shoots like a champ. So I thought that could be the culprit.

    It was exactly what I expected. Took me a day and a half to get it all out of the .300. I took it back the next day, fired a couple of fouling shots and it was right back in the groove. Needless to say, I have settled on my best load and will not be shooting it as much. I may fire up to 10 or 15 rounds on Wednesdays when we open up the long range section.

    I have thought that I would go back to my old method of cleaning the bores after each session at the range. Is that too much or am I on the right track.
    How many rounds or how often do you fine shooters clean your bores?

    I clean my .223 after every time i go out. The guys who built my new 260 are avid bench rest competitors and they emphasized cleaning after every 20 rounds PERIOD, but that's for 1000 yard competition. 50-75 is probably a more real world number.

    they also turned me onto some new cleaning chemicals that are simply amazing. I just use the accelerator with the patch out, get the bore wet with a mop wait 20 min and push a couple dry patched through, a voila; surgical clean. If its really dirty i sometimes use a nylon brush but only about 5-10 strokes.

    I'm another one of those guys that were taught - you shoot it, you clean it, after each time.

    Well, gentlemen, shoot and clean is what I have always done and never ran into a problem. Sometimes it may be best just to listen to advice but do what you know is right.
    Thanks, those are the answers I wanted.

    Keep it clean. If you notice a decrease in accuracy while shooting, you have already gone too long without cleaning.

    It depends on which rifle I am talking about.

    My 308 with a match grade SS barrel gets cleaned after every time out. Same goes for my AR. Now my remmy 700 gets cleaned 3 times a year. Once before the ground hog season once during and once after. That is it. It has never showed any signs of groups opening up over time either.

    My rimfire RIFLES get cleaned once a year. Pistols are different both are semi autos so I clean them more often. Maybe every 2 times I go to the range they get cleaned.

    Depends on the rifle. Some are more prone to metal fouling than others. You did not say the age or wear of your barrel, but you might consider trying a product like JB Boreshine after your next cleaning. Smooth lands gather less copper. Last time at range, watched a SERIOUS BR shooter, working on groups less than .25 MOA, cleaning every 10 shots. Could not argue with what I saw him putting on paper. However, that is extreme, and for the average target shooter, IMHO, overkill.

    I have just about done away with brushes in my rifles.

    I start with patches soaked in Kroil and let it sit for 24 hours.

    Then, more kroil followed by a series of solvents with patches until they come out clean.

    Learned this from some local BR shooters and it is working out so far.

    Depending on the gun,I will clean when I notice a change in the way each one shoots. Some are 10 shots and clean,others will go much longer.
    I generally clean all the guns I shoot at a range session within a couple days after going home just as a habit.
    Now when it comes to hunting season,the guns do not get cleaned unless something happens while in the field.Then I will sight it in after cleaning.

    On the subject of copper fouling,my new 25/06 is one of the worst copper fouling rifles I've ever seen.So far I haven't found any product that will take all the copper out.I've tried several liquid cleaners,and a couple foam cleaners.The rifle is just a copper mine,even after hand lapping the barrel twice.
    A member of another forum sent me a link to something that I'm going to assemble and try.It seems to work,for those that have tried it.

    Making the Surplus: Homade Electronic Bore Cleaner

    If this works,I'll be happy.Then I'm going to try the Tubb's Final Finish bullets out on the 25/06 and see if it will help with the fouling problem.If it doesn't,then I'll just put a custom barrel on it.

    C3 the rifle is a new Remington M700 Mil Spec 5R stainless .300 WM. I also have a newer same type rifle in .308 and .223 and haven't had any problem with fouling in them. I was also pondering if it could be due to excess copper fouling from the Berger bullets I have been testing in the .300. The .308 gets mostly Sierra Matchkings and a few Accubonds.
    I will stay with the Bergers this year since I have developed a very accurate load and will be using them on my upcoming elk hunt in October.
    I won't be shooting the .300 much except for periodic practice sessions at 300 and 400 yards and then clean it that day.

    Well with that target rifle of mine, I usually give it a swab or two with Hopps copper solvent and let it soak for an hour or two between swabs and dry patch it then light oil patch it followed with another single dry patch and put it away until next session. This is around 80 to 100 rounds per practice sessions and matches. I dont give it a "super" clean until about 300 rounds. I get to the range about 6:30 A.M. and as soon as they open I put a few fouling shots through it and check my 100 yard zero at the same time. Then according to what the ballistic calculator says after entering temp, barro pressure, wind, etc.. I make up my come up sheet for the fireing lines at the 1000 yard range. The fouling shots seem to help. I do clean the rifle every time I shoot it but I don't "scrub the hell out if it" after every time I shoot it. Barrel life is critical to me and the procedure I've adopted seems to work well. I dont have much if any copper build up as the Krieger barrel is hand lapped. It stopped showing copper for the most part at about 20 rounds at break in. Actually I've already ordered another barrel before the one I have now starts to loose it's precision. I figure I've got between 400 to 500 rounds left before this happens. Developing loads has used up quite a bit of this barrels life as far as precision is concerned.


    What your going to see with the .300 Win. Mag. is throat errosion before the actual barrel goes. Especially if your loading ramped up loads for higher fps muzzle velocity and using 190 + grain bullets.
