[QUOTE="MontanaRifleman, post: 899806, member: 11717"] Jeff has given you good advise and I agree that you probably have never got all the copper out before. One thing I would do different is shoot one and clean for the break-in instead of 3 or 5 shot groups between cleaning. I say this because in my experience (and I have a good bit of experience in this with factory barrels) the first shot is responsible for most of the fouling laid down in the bore. After that, successive shots do little to "smooth" out the roughness. How do i know the first shot lays down most of the fouling? Because it takes almost the same amount of effort to clean after 1 shot as it does after 20 or more shots. I am going to be quite honest with you based again on my experience. I have put a lot of effort into breaking-in used factory barrels and if I could go back knowing what the result was, I would not do it again. Too much effort and time for too little gain. Some factory barrels will just never break-in well. If your barrel is pitted and/or fire cracked along with deep tooling marks, etc., it is pretty much a hopeless case as far as break-in is concerned. To do a break-in with Bore Tech (and there is no quicker way to do it right) you will run wet patches through the bore until color starts to fade. then soak and use a nylon brush to scrub the bore, then wait for 20 min and start running wet patches again... do not run dry dry patches between brush scrubbings... it only wastes time, patches and solvent. Repat this cycle until you see no color on the patches. you will probably run 10-20 or more patches between scrubbing and soaking, less toward the end. You might do half a dozen or more patch and scrub cycles per cleaning session which might take you 2-3 hours or more. It might take you 20 cleaning sessions or more to do the break-in. Been there, done that. It took me 3 long sessions (3 days) at the rifle range to break-in my Senderos. Another less labor intensive way to do it is with Wipeout. You spray it down the bore and let it soak for 4-8 hrs then run 2 patches through and repeat. 7 or 8 of these cycles will usually clean the worst of bores. Wipeout Accelerator will speed the process a little but you still need let it soak for a good while. IMO, If you're getting 40 rounds of acceptable accuracy, that isn't too bad for a factory rifle and if it's "just a hunting rifle", well practice alittle with it, clean it before hunting season, foul it and sight it in for the season and leave it alone. If you're looking for a precision LR rifle, get a new custom match grade barrel. [/QUOTE]
