slug ricochets

Is it possible if you were shooting straight at a target 50 yards away for a slug to bounce back and hit you?

If your shooting something with that much velocity and energy in a straight line how could it come back that far at a 12 degree? angle or so in the opposite direction just from bouncing off of something? Doesn't the lead get squished when it hits stuff straight on and if it hits at an angle its not likely to come back your way?
