No handicap needed for the Remington Autoloading Shotgun
After introduction, it was quickly adopted by trap competitors; didn't hurt to have the great Rolla Heikes and Charles Budd on board (Heikes had used a Remington double to win the 1st 1900 GAH at Targets, and both used Parkers at the 1901 Anglo-American Match)
J.J. Banks then won the 1907 GAH
And Fred Harlow won in 1908
Forest & Stream July 4 1908
