Yes, he is a fantastic shot, and that Perrazi with the Over/Under barrels is a fine shotgun- but his crow technique won't 'fly" here, where I average 500 dead ones a year- all close in shots with a unplugged M12 12 gauge and AA skeet 9's- I won't waste my time on "bluebird days" for crows or decoying barn pigeons, and I wear the "full Monty' of camo as i do for waterfowling and turkey- and the spec. Op. mantra of "no rattle- no shine'
But then, I am not a Limey or a clays or a O/U man-
I've been shooting crows for nearly 40 years and have tried it all. FWIW my annual average is higher than yours. Anyone who uses AA Skeet 9's, regardless of gun, on crows is either ignorant of the fact larger shot can do everything the 9's can and then some or they don't mind being terribly handicapped and wounding birds that would otherwise be dead.
