True, I probably used the wrong term.
Cast is more typically applicable to shouldering a shotgun quickly to acquire a target.
I should have known this being a Grulla owner.
I wasn't trying to check you or anything
The topic of butt plate design is very interesting however, I've heard a lot of different theories as to why some were curved like that and some more so (like the Ohios, Shutzen etc) best I ever came up with was that it was a style preference. Even some of the original Hawkens were made with flat shotgun style plates.
