Seems fitting, as I've been messing with a new to me Sako that really needed some copper fouling removed. That was part of the reason I got it for so cheap. The gunshop owner knew I'd get it taken care of though, and it's been a learning experience because I've never had a rifle with that much copper in it!!!!!!
Really bad picture, but you get the idea^^^
Went as far as making my own bore guide as well:
The small action Sako has a very small diameter bolt body, and none of my bore guides would fit it.
The first thing I did was buy some products I found at the local gun shop/hardware store. That was Barnes CR-10. That stuff didn't even touch the copper in the barrel, and I used it as the directions said.
Next I said f it, and ran some sweets 7.62 down it. Making sure I did not leave that crap in the bore for too long. The rifle was not shooting horrible, but still not MOA like I thought it should:
I was waiting for the Wipe out, that I ordered online to come in. After the wipeout, the patches looked like this:
But after shooting, the rifle looked like it wanted to collect copper again. At this point, I said screw it and attacked it with some flitz metal polish. That stuff seemed to help reduce the copper fouling the next time out.
Now, I am just using my shooters choice, that I normally use on all of my rifles and getting patches that look like this:
I let the shooters choice sit in the bore for 15 minutes, then swabbed it out. This was before shooting the rifle!!
Since the groups looked like they were slightly improving:
Well, the majority of the bullets were landing in roughly the same spot, I figured It was time to glass bed the rifle:
Now it's shooting like this:
From here on out, I'll just clean it the way I do the rest of my rifles and it should be good. If it starts collecting copper, I'll hit it with that Wipe out/patch out stuff. It seems like it works well on the copper, and is not as harsh as the Sweets 7.62.
This rifle should turn in sub moa groups at 400 yards now, but will need to be rung out and checked.
The other day, I was losing daylight, so I just painted the yote real quick and fired off some shots to check how it was going to do at 400 yards.
First 3 shots hit in the neck, then I fired off 5 more at his head. Should be a yote killing machine now..
100 yards was too easy of a shot on this furry rat..
In the back of my mind, I kept thinking this would probably be the perfect candidate to try some of that dyna bore coat JB is always talking about. I'll bet if a guy were to clean the bore down to bare metal, then apply that DBC, that would solve a lot of problems...
