I'm probably over analyzing this but can't seem to get it out of my mind. Ok, we all know that your action (be it a rifle, shotgun, handgun etc.) needs lubrication but not too much. When I lube my guns I'll wipe down the bolt and interior of the action with some sort of oil (usually Breakfree CLP or LP) to make sure I get a good coat on all the moving parts. Then I'll wipe off any excess so it doesn't run, drip, etc, to where there's just a film on the parts. Before shooting I'll swab the chamber with degreaser to make sure it's dry. Lately though I've still worried about the possibility of a slight amount of oil transferring from the action to the ammunition as it's cycled from the magazine to the chamber and possibly causing too much bolt thrust. Mind you, I've never had my actions running or dripping with oil but do like to make sure they have a good film on them for both rust protection and lube. I don't see any on the shells but sometimes they feel a little slick, not wet though. Not sure if the brass is just that smooth or it's the oil from my fingers or a combo of both. So I know the ammo shouldn't have oil on it due to the thrust issue, but am wondering if a miniscule amount happened to get on a cartridge could that small amount be dangerous too? Or am I being too paranoid? Thanks for any input.
