One time when I had recently gotten my 10/22, I stupidly let my friend shoot it, sort of. Well, apparently he put the banana clip in backwards, and had it jammed in there and was now wondering why the gun wouldn't fire. I had to walk back up to the house and partially dissasemble the gun to get the magazine out.
His excuse: "well on my gun the clip goes in like that". For reference, his gun is a yugo sks, with the stock internal mag.
May the gun gods curse you both.
