Compak Sporting is a sporting, shooting activity involving clay pigeon shooting based on Sporting Clays. The name Compak Sporting is a protected, registered trademark with sports rules, owned by F.I.T.A.S.C. - Fédération Internationale de Tir aux Armes Sportives De Chasse This game is a variation of Sporting Clays.
As the name suggests, Compak Sporting is a "compacted" game of Sporting Clays, Let's look at Sporting Clays first - this is a shotgun sport usually spread over 12 to 36 stations (shooting areas) occupying around 200 acres (0.81 km2), presenting 2 or 3 different clay target s at each. One shooter will shoot the targets, followed by the next and so on. With Compak Sporting the space requirement is considerably less, and a squad of up to 6 shotgun shooters, (5 actively shooting), will stand in a straight line, each on a marked square (1 meter by 1 meter) and spaced 3 to 5 meters apart (i.e. the shooting line will be 12 to 20 meters long). In front of them will be the "target area". This is a rectangle 40 meters wide by 25 meters deep and positioned 4 to 5 meters in front of the line of shooters. (If the shooters are numbered 1 to 5, the rectangle will be centered on shooter 3)
The target area should be marked with four flags defining the four corners. Clay target s will be thrown by clay pigeon trap machines, of which there must be a minimum of 6. Every target thrown must pass over at least one side of the 40 x 25 meter rectangle. E.G. A target can be thrown from outside the rectangle and land inside, it can be thrown from inside the rectangle and land outside, it can be thrown from inside the rectangle and land inside (e.g. a Teal shot)or it can be thrown across both sides i.e. thrown from outside the rectangle and landing outside the rectangle but crossing some part of the rectangle during its flight. Shooters take turns shooting the various targets - these can be single targets or double targets (instant pair or report pair). Targets are released on a random time delay (0 – 3 seconds) after the shooter's call. There are numerous rules defining compulsory targets, traps, triggering systems, shooting stands, targets, trajectory-setting-tables, guns, ammunition etc.
