I hunt with an 870. I load the magazine when I leave the house but I don't chamber a shell until I'm setup. I don't do much moving but if I do, I empty the chamber beforehand. I've heard a few stories of guys using an 870, falling, the but hits the ground causing the pin to strike the primer and causes an accidental discharge. It messed with me and I don't want to take the risk with my particular shotgun. I empty the magazine when I get home.
