In 1892 the Interstate Manufacturers and Dealers Assn., “Interstate Assn.” took over organized trap shooting. The Interstate Association’s purpose was “for the encouragement of trap shooting, in giving tournaments to foster a sport that is deservedly popular to bring together experts, semi-experts and novices, to safeguard the interests of both, and to show how a large trap-shooting event should be run.” It quickly organized the first Grand American Handicap at Live Birds, under Revised Hurlingham rules, for spring 1893. Twenty-one shooters paid $25 to compete.
At the 1894 GAH, guns were limited to 12 gauge and 8 pounds.
