The Fifty Caliber Shooter's Association, Inc. (FCSA) was established in 1985 by a small group of dedicated people who set for themselves the mission to advance the sporting uses of the .50 BMG cartridge. The FCSA is a non-profit organization registered in Tennessee.
The objectives of this organization are to unite all persons within its jurisdiction and provide a vehicle for communication and competition to those people who enjoy all the sporting aspects of the .50 cal. BMG cartridge, and all wildcat derivatives of the .50 cal. BMG.
The FCSA provides a quarterly magazine, a suppliers list and consulting information on fifty caliber rifles and ammunition to all it's members.
