[Raven]

An old friend told me that shooting skeet
is never like the real thing

because when your hunting the unexpected happens
like your takin a wiz and birds suddenly arrive

or a bird flies directly at your face

or your just grabbin a cup of coffee

the point being...

i learned to shoot whether i was kneeling ,
standing, sitting ,or laying down on my back...
( saying pull with gun laying on the ground)
to the point that i was "rarely surprised"

and could always grab (snatch)
my shotgun at a seconds notice
and snap it into place from any position.

i don't know if this suggestion helps
but it sure helped me
be ready in any situation
