Iqbal,
I find O&Us are more pointable , and have appreciably less muzzle flip.
The snob thing about S/S at formal driven shoots in the UK is more or less a thing of the past, though it does rear up every now and then.
I too use an O&U, and a semi auto for pigeon decoying, where one can fire off up to 300 shots in a day.
Mpofu.
