The thing balanced across my wall thickness guage is a homebrewed pitch gauge. I'd just as soon measure (in degrees of angle) and layout pitch with this as stand the gun in the doorway such that the breech touches the casing and the muzzle is X distance away and then attempt to scribe a line on a piece of masking tape on the butt by sliding a chunk of plywd and pencil around the stock face. To each his own. One useful thing about zero pitch guns is that they are huge framing squares and can be used to "try" rectilinearity. Now if you had a house which had flooded and wracked, you'd want to check your house against your gun, not vice versa. But as a gun, for me the protruding toe does make the butt slip down at the shot.
