I've had a Sako 75 Hunter in7mm/08 for about 3 years, but I'm about to get rid of it. I can't seem to get rid of the copper fouling, and I'm not getting any kind of decent accuracy.

I may have created the problem when I first got the gun, almost NIB. I called Sako customer service and asked whether the barrel needed to be broken in, and they said no. I messed around with the gun for a while on the range, trying a couple of different scopes until I got one I liked, so I may have shot a couple of hundred rounds and only pushed a patch with CLP through the bore -- no break in or heavy duty cleaning. Then I noticed that the grooves in the bore looked like a penny -- very noticable brown copper deposit. It took me forever to clean it, then I went through the break in process, which also took forever.

Killed a deer with it a couple of years ago, but it's set in the safe since then. I dusted it off the other day, took it to the range and couldn't hit jack. Got home, and guess what, the damn copper was back. I've pushed a dozen patches saturated with Butch's through it, and I've still got a good deposit.

My question is, do I have "lemon?" Or have I somehow messed up a perfectly fine firearm? I'm stumped. I don't have a lot rifles, but I've never encountered this before. Thanks.
 
Pick up a bottle of Sweet's 7.62. It is an aggressive copper remover. It has an extremely harsh smell (ammonia), but it works great. Follow the directions on the bottle.

Don't let it sit more than 15 minutes at a time. After a while, if you are not happy with the results, use a bore brush (however, it will destroy the brush because it is made out of copper.)

With a little (or a lot) of elbow grease, she'll be shooting as good as new before you know it.

Clean back to shiny metal after EVERY shooting outing until it stops copper fouling.
 
Get yourself a can of WipeOut foam. Fill the bore, return in the morning and patch it out. The bore will likely be copper free, if not repete. I`ve never had to do more then two treatments.

I`ve been useing this stuff for the last year or so and it`s the eaiest way to remove copper I`ve found. The cleaner has little odor unlike Sweets or Shooters Choice Copper remover, and is safe to leave in your barrel. I follow with a couple of patches with CLP or FP-10 to remove the cleaner and a dry patch before storeing.

Be careful when filling the bore. This stuff expands to fill it like the canned foam insulations. I block the breech with a twisted paper towel and give a one or two second squirt from the muzzle, then check to see if the bore is full. It doesn`t take much, watch the gas vent in the reciever ring.
 
The best, surest method for removing copper in a barrel is the Outer's Foul Out system. Probably nothing wrong with that Sako's barrel. Kind of silly to "break in" the barrel after you've run a couple of hundred rounds through it. ;)
 
Thanks, guys

Finished getting the copper out, took it to the range, and after a few fouling shots, the gun shot dead on. I'm new to this, and I guess I didn't realize how tedious breaking in a barrel can be.

Rockstar, I appreciate your help, and I hope you'll be open to what is intended as constructive criticism. Slightly snide or condescending remarks such as, "kind of silly to be breaking in a gun after 200 rounds," could tend to discourage guys like me from taking up shooting. Not a big deal in the big scheme of things, but this stuff can add up over time. I'm reminded of some of the threads about rude gunstore employees. When I checked in at the range today, I saw a target style that was new to me, and I asked the guy behind the counter what it was for. He said, "It's to shoot!" and turned back to the cash register.

Thanks again for the advice, everyone.
 
Flynt,

I don't believe Rockstar meant anything derogatory in his comment. But ,it is hard to guage the tone and intent of people on the internet, sometimes. What he was saying was that you can't really break in a rifle if it already has a couple of hundred rounds through it.

That is why he put the "winking smiley face" at the end of his comment. It was just a little jab, no harm intended.

But I agree, sometimes people tend to be a bit snobby. However, I think you will find them in any field/profession/hobby.

My son's 7mm-08 copper fouls like crazy, but it's still the most accurate rifle in the family. I'm another Wipe Out fan, after being unable to get multiple applications of Hoppe's Bench Rest and Barnes CR10 to work. I can't find it locally, and I get it by mail order from Midway USA (www.midwayusa.com) .
 
Where does one find Wipe-Out in AZ. I'd rather not have to deal with mail-order if I can get it locally.

You might try here, but living in AZ, you'll come to find that anything new will often have to come from somewhere else. At least in my area(rural).
95% of my purchases are out of state because they just don't have it in AZ, or the price is so much better elsewhere, even figuring freight.
