To clarify the record for hand-thrown targets with a pump....
"On July 19, 2000 Tom Knapp, with his pump Shotgun in one hand, threw eight clay targets in the air with his other hand and broke every one of them with individual shots in an amazing 1.87 seconds creating a Manually Operated Pump-Gun classification."

Semi-autos are still faster, but I figured we may as well have the right numbers for comparison.
