[QUOTE="freddiej, post: 1926047, member: 26227"] I have a story about a family that would never clean their guns, the son came in with this 1950/51 Winchester M-70 in 30-06, it had never been cleaned since it was new. I can not say how many rounds were through the gun but it had to be a lot. The son came in with the symptoms, "popping primers and excessive pressure with factory ammo". I tried to get a 30 cal jag through the bore with a patch, no go, I thought the barrel was miss marked and it was a 284 or a 270. well I slugged the bore and came out with a 0.304" groove diameter and a 0.296" land diameter. so out came the Sweet's 7.62 and the JB Bore Paste, also the Bore Tech C4 Carbon remover, and the nylon brushes.. 3 weeks I worked on that bore getting the carbon, copper, powder fouling, and whatever else was stuck to the bore. patch after patch was cobalt blue, black, silvery grey, and a multitude of other colors. Once I was able to get a Jag in the barrel with a patch I used JB Bore Paste to mechanically scrub the barrel of what ever was being stubborn. after 3 weeks the groove bore was 0.3079" and the primary bore was 0.2999" and it was polished. I went out to test fire the gun and was pleased the gun kept 1/2" or just about 1/2". I gave it back to the owner and he messed it up again in just about 1.5 years. I had to repeat my cleaning process all over again. I darn near refused to give it back to him for abuse of a classic firearm. [/QUOTE]
