I'm headed up north next week after some snow geese and I'm taking my new pedersoli 12ga with me. Problem is I have 0 experience cleaning a BP gun at camp. I will have access to water and I'll be at my car but I'll be limited on how much fuel I have for the stove. There's a grate for the campfire I suppose I could heat water on.... what are your guys cleaning tips for multiple day hunts? What should I take with me to make the process easiest? Does using BP substitute make not cleaning okay for a few days?
