Cast on/cast off?

[AmarilloMike]

With the gun pointed away from you bending the butt to the right of center is cast off. Bending it to the left is cast on. This rule applies if you shoot right handed or left handed.

Cast off is for right hand shooters.

How 'bout this for cast-off? It actually appears to have less than Mr. Orr's gun. This my 1906 vintage NH.
