A short time after a BFG impact with any surface or object, the game basically performs a cluster of hitscans radiating from the player in the direction the shot was fired. Thus the most effective BFG strategy is to stand to the side of an entrance to a crowded room, shoot the BFG at a wall, and strafe toward the entrance until as many enemies as possible come into view. Get the timing right, and you turn the room into an uninhabitable no-man's land until your six shots run out (ten if you grab the ammo backpack). I miss those days :)
