You are correct, and Thanks!
I was purposefully brief, because its a guys business, and its very popular, and easily contacted.
Brian is a devotee of the Churchhill method of shooting.
Hes been doing it a long time.
So if you like that style, he can help you attain it.
It starts with footwork, proceeds through posture, All the way up through how you hold your head.
Then they work on the leading left hand, and the raising of the gun to the face and the rolling in of the shoulder behind it.
Its a muscle memory thing, its a style thing, and if a person practices it they will become a better shotgunner.
In the competitive arena, where different techniques are best applied in different places, its a good place to start but its not the be-all end-all.
But when you get done, if you apply the principles, and you adapt your stock to the provided dimensions, you will shoot better.
And look better doing it.
