[QUOTE="Old Rooster, post: 2982700, member: 108576"] My brother bought a brand new Tikka in 7mm 08 and sent me pics of great groups.I went down there to go on a hog hunt with him but after 3 boxes of factory ammo it wouldn't group.One of the auto parts store had some Free All spray.We used to use it on stuck bolts/nuts or screws and it would free it up.There is a chemical in Free All that attacks carbon and I use it with great results so I bought him a can.Even after cleaning with Wipe Out and again with Bore Tech Eliminator and sprayed a patch with Free All and you should have seen the carbon!We cleaned the carbon out and there was a layer of copper we cleaned out and another layer of carbon.We cleaned that rifle all afternoon into the night and finally got all the copper and carbon out and it returned to shooting good groups again. Lesson is:Carbon will hide under copper layers and vice versa.Don't be afraid of Isso ot J B Bore Paste to get that out. Free All is a great carbon finder!I spray it on a patch and run it through the bore to see if carbon is present. [/QUOTE]
