Prior to World War II, George Jones represented the Walthamstow Ensign Club, and in 1939 represented Great Britain in a match against the United States at the Ham and Petersham rifle range near Twickenham Ferry. After the War, he joined the Twickenham Rifle Club, and shortly before the 1948 Olympics, won the Scottish meeting of the National Small-Bore Rifle Association. Selected for the London Games, Jones took part in the small-bore rifle 50 metres prone event, and finished a creditable 18th out of 71. The year after the Olympics, Jones won the National Small-Bore Rifle Association British & English Championships at Bisley. In the annual match against Sweden in 1950, Jones scored 40 consecutive bulls, as he helped Britain to a three-point win over their opponents.
