I have used it for 3-4 years for my TC Omega, per the instructions on the CD that came with the rifle. Never had a problem. Shoot > wet patch > dry patch > reload and repeat. Then when finished and barrel is clean...run 1 or 2 bore butter patches through for storage. Remove BB with wet and dry patch and you are ready to shoot again. Rem oil, or any other high quality oil would be just fine, or even perhaps better. However, my barrel is clean as a whistle (no rust) and is very accurate with 2 50's and 250 SW. All I have done is follow directions per that CD. Has worked thus far and don't see any reason to complicate things.
