I store my guns butt up for that very reason. However, over time all oil and grease also wicks upward just as though there were no such thing as gravity. So, whatever excess lubricant is in the action will end up wicking into wood. It requires an amazingly small amount of oil/grease to fully coat the working pieces. Don’t worry about getting it into every nook and cranny—the wicking will assure it gets there.
