I have fallowed Stans work through the years as pioneer in shotgun barrel modification. Over boring - forcing cone lengthening -Choke tubes --Had one of his over bored Tm-1 tuned out to .745 --Just ran across one of his big bore single barrels, fitted to a browning lighting trap - adjustable rib -.800 bore -Isn't that just .005 smaller than a nine-gauge barrel? basically a barrel without a shell chamber? - Comes with four choke tubes. .780 - .770 - .760 - .750 tubes-Making the full choke larger than any of my cylinder barrels. -- my question is, would I need special wads to shoot a bore that big -- Or did Stan finally go over the top? Great piece of shotgun history, but at the seller price I would have to shoot it. Just looking for other big bore shooters input.
