This question is out there on the edge (maybe beyond the edge) of any cast bullet topic, but here goes. I've been doing some wintertime pellet gun shooting, and wanting to keep the bores from rusting in my damp basement, I looked at the pellet gun oils available from Crosman and Gamo. Turns out both of these products have stern warnings NOT to use them in the barrels of air guns--particularly in break-barrel guns. I sent messages to both of the companies, asking why the warning was there, and got the royal runaround (and some lies) in both cases. I also asked what kind of lube or preservative should be used in a pellet gun barrel, and I got no answers there as well.
So here's the question for my knowledgeable and well-informed colleagues of the CBA: (1) What is so dangerous or stupid about using ordinary preservative anti-rust oil in a pellet gun oil? (2) If using oil is such a bad idea, what kind of product should be used in pellet gun barrels?
Any and all assistance is welcome!
