I use Wipe out also and it works great brought the accuracy back in my one gun that was 26 yrs. old. But I would recommend that you go to a hardware store and buy about 6 in. of 1/4 in plastic tubing. Insert this inside the tubing that comes with wipe out can. This will allow you to insert in a few inches inside the breech part of the barrel and not get a back up of foam all over your gun and stock. Then plug the other end and let the gun sit flat over night and patch out a few times until the patch is clean. You will get a blue green patch the first few times telling you it was removing the copper. Its well worth the purchase. It gets out the carbon ring also just try it and you will be happy.
