Well i was going through some old ammo at the station and found these 12g round that are only about 1 3/4" long and say flare burn time 6 sec for marine use only. Well i dont work on the water so i made the comment "what the hell are these for" And an MPO responded "for shooting down the hallway on midnights, hahahaha" I thought to myself these have potential fun out in the country written all over them. Any experience with something like this? What kind of range or flare up were talking about?
