Well, dove season started Monday. Grabbed my Mossy 835, an abomination of a dove gun, I know. But it was in my bedroom and was handy. Monday morning I pulled it out and it being fairly new i decided to make sure it had a plug. one shell, two shell, three shell.. Great, I'm gonna have to cut a dirty stick and put it in my gun. maybe there's something in the truck that will work. just so happens that the barrel of a regular Bic pen with the ink cartridge removed is exactly the length of two 2.75" shells. just a tip if you find yourself without a plug but with a pen.
