It's standard practice, I believe to put a thin film of oil in a bore before putting your gun back in its cabinet. Two questions, if you'd be so kind. 1. Is it best to put what you consider to be a thin film on the bore and then leave it? Or is it more advisable to put a little more oil in the bore and then run a dry patch through to remove most of it, leaving a thin film? 2. In the event of a thin film of oil not being quite as thin as one had supposed, is it better, for people who store their guns butt down and barrel up, to leave a snap cap in the chamber or pack the chamber with paper towel to prevent oil seeping into the action?
