Jackson was eventually sent to Selfridge Air National Guard Base in Michigan to help form the first Air Force Rifle Team and trained at Palm Beach Air Force Base in West Palm Beach, Florida, during the winter months. His next international stop was the 1952 ISSF World Shooting Championships, where he took home gold in the 50 m rifle prone position with 60 (individual and team) and 40 shots (individual) and the bronze in the 300 m standard rifle (individual) and 50 m rifle prone position with 40 shots (team). He then traveled to the 1952 Summer Olympics, where he won a bronze medal in the 50 m rifle prone event and finished 12th in a field of 44 competitors in the 50 m rifle three positions tournament. Upon his return to the United States, he discovered that he had been promoted to the rank of Captain.
