Tom Knapp was good, in his day, but his personal record was 10 targets.
I heard that Ad Topperwein once shot a 25 straight at FCGC in Savannah with .22 Shorts.
I have seen Tim Bradley do his exhibition shooting at FCGC in Savannah, and was under impressed. He missed a lot.
I have seen Jon Krueger do his exhibition shooting, and he was much better.
But, the best I've ever seen in person is John Michael Morris, from Georgetown, SC. He is just over the top. Almost never misses. I have witnessed him run a 25 straight on the skeet field in 60 seconds, from the hip. I've seen him run a 25 straight on skeet while riding a bicycle, steering with his left hand and shooting from the hip with his right hand only. And, John Michael has never had a big sponsor giving him free shells like the others do. He can shoot just as good with the shotgun upside down and over his head as he can from the shoulder. He is a friend, but I envy his ability really bad ........
