You know, eightbore, what I like so much about shooting shotguns is there is no such thing as "the only right way". As you said, "to each his own". I shoot with my head stuck up like an ostrich and sometimes actually hit something. Others cram their heads down like they're butting heads and they often hit what they're shooting at. Some use a sustained lead, others a swing through. Me? I haven't the slightest idea--never think of it and couldn't care less. I just look at the target 'n shoot. And I'm happy. I avoid like the plague reading any "how to" stuff on shooting. Feeble as my brain is I'm sure I'd find out how I do everything wrong 'n it'd screw everything up worse than it is now.
P.S. I too have one shotgun with sandpaper glued on the butt--go figure.
