The problem is, I have been working on the inside of the barrel for 6 hours now. I have ran a good 40+ patches and scrubbed the barrel with a brush 3 times. I have been using Shooters Choice patches, and then 2 patches of Sweets 7.62(or whatever the number) then coat the brush with Sweets. I then scrub for 10 strokes, then let the gun sit for 20-30 minutes. Then run more and more patches of Shooter's choice. The patches are still coming out blue. dark blue after scrubbing and then lighten up but never going clean.
So When I bought this gun I had the place scope the gun (supposedly) and they said the barrel looked great. I bought the gun sight unseen other than pictures. Like I said the gun is in fantastic shape but I am beginning to wonder if I made a mistake. I am wondering of the guy who owned the gun before me lost accuracy so he traded it. I am thinking the barrel could have been fouled because no way did someone that knows guns let this barrel get this bad.
When do I know when to stop cleaning? Is the stainless barrel having something to do with it? I have never had a stainless gun before so I don't know what to expect.
Hey Sako, it sounds like you are doing things right, but as was mentioned, you are getting at least some reaction from the brushes. When I've he'd to clean something like that, ( which usually isnt mine), I dig out the JB bore cleaner. Also, if it is severely fouled, I learned a long time ago, that if you boil some water, and pour it down the barrel, get it good and hot, and while it's hot use the JB bore cleaner, it works amazing. The heat, opens the pores of the steel, and let's the cleaner get more of it out. I have done this also with liquid cleaners as well, and it really makes it work then. Give that a try, I think you will get it clean then. It dosen't harm the barrel, but just don't bang it around while it's hot. I usually rest the barreled action across a couple of sand bags while doing this! Hope this helps! Take care buddy!
