Shooting at the 1924 Paris Summer Games:

Marcus Dinwiddie of the United States was the youngest shooter in the competition, at 17. He shot early in the day and broke the Olympic record with 396. But later in the day, France’s Pierre Couquelin de Lisle bettered this with a world record 398, using .22 ammunition from the U.S. Cartridge Company. Wallechinsky described the cable Coquelin de Lisle sent to his mother, “Am Olympic champion. World record beaten. Will arrive Tuesday morning.” Coquelin shot 38 tens out of 40 shots. Some of the shooters used ammunition pockets, although these were not allowed at the range, for supporting their arms.
