Mark, remember that you only use 2-3 SMALL drops of the chamber oil and obviously you never dry fire the rifle (instant ruination potential). You can partially (or fully) move the cocking arm up and down to spread the lube. I would even leave it overnight, then shoot it with a pellet. You may even get a couple shots that will "detonate" the lube (bang) no big deal unless you overlube. Shoot the rifle into an old phone book. An inch or so penetration should be about right as far as power goes. rough estimate anyway. . gpod luck.
