Never been shy about how often I clean guns (almost never), but
I keep a combination kit that I cobbled together from an Otis kit and a regular] bore snake, I use the Otis tin (think big shoe polish can). I have seen too many times on hunts or in the field when someone falls and “muzzle punches” the ground. The other time being if you are out in the rain all day or have had some reason to ford a stream/river/ocean/bay/swamp. I run the Otis cable from the chamber down the bore and drag along the bore snake afterwords just to get it back in the game if necessary.on rainy hunting days I will wrap the snake in a couple patches and drag it through. I also keep about $5 worth of rolled up $1 bills. Due to the high cotton count I use them to dry the water under a free floated barrel. FWIW when I bed a rifle use them as a measuring stick to ensure the clearance is sufficient (two layers of blue painters tape is slightly thicker than a $1 bill).
Cheers,
