Sorry guys, the IFA recognizes using standard target darts from a standard 4 ft. barrel for long distance shooting. Jeff Boumier of France holds the officlal IFA world Record (I think it was 60 meters ???) back in 2010 or so. The French national organization has disbanded since then.
Target face was 24 cm diameter, only need to hit 1 of three darts shot. Bruce Bell of the USA held the first WR, 46 meters. Both used standard, store-bought 0.40 cal. target darts ( 0.8 gm weight). Official rules - start shooting from 20 meters - standard target height above ground, center of the target fce at 160 cm (5 ft 3 in.) shoot 3 darts, one must stick. If it does, move back 2 meters (@ 6 ft), and do it again. Round robin, last man standing wins.
Google "The breath of Zen" - also in France - if you want to really see long distance dart shooting at its perfection .... 80 meters!
