[QUOTE="freddiej, post: 1765256, member: 26227"] I just got done cleaning the carbon and copper out of a 1950's Model 70 338 Win Mag. my go to carbon cleaner is Bore Tech C-4, my go to copper cleaner is wipe out-- patch out, then again, I have such good results with Montana and Hoppe's, nothing does it better than Wipe out products. this means the "accelerator" before patch out on nylon brushes and soak the bore in the two products together. then if it is really bad, like the 1950's M-70, I use a really unusual combination I discovered by complete accident. I first put down accelerator, then patch out, after 20 minutes I start in with J&B Bore Paste and keep agitating until the patch out is a gel. then run a patch through and start all over again. nearly 70 years of copper and carbon build up came out in a couple of days between repairs on other guns. the gun was supposed to be a 1/2 MOA gun and has degraded to 1.5" gun last week. they wanted a new barrel and I asked if I could try to save the barrel.. I did, the gun now shoots 1/2" groups for me at 100 yards, that is not C to C that is edge to edge. 200 yards it is 3/8" C to C, 300 yards it is 1/2" C to C. this is one hell of a nice 338 Win Mag. I am going to offer to buy the gun when the guy comes to pick it up today. [/QUOTE]
