Tin of lubed felt wads and thin "overshot" cards. A small leather bag with turnscrew, wore spring style tow/patch worm, cleaning patches, ball puller, and length of cordage for tow & toggle. Tin of prerolled and filled shot cartridge/cups. Tiny tin of homemade patch/wad lube also used for metal protection and sealing the edges of the pan. Short pieces of thick "toothpicks" or BBQ skewers to plug flash hole. Small antler priming flask. A bit of rag for wiping up lube messes or wiping the pan. Vent pick is tucked into a seam in my bag flap.
Pan brush is lost somewhere in the bottom of the bag as it is only used to remove dry prime if the gun didn't get fired.
Often lately whether it is squirrels or deer I have been forgoing the tin of wads in favor of a small leather bag hanging from my shot pouch strap that is full of overshot cards, lubed balls of "faux-tow", and lubed felt wads. It hangs next to the pouch and can be tucked inside if need be.
