About SIM-X

SIM-X Tactical Solutions was founded in 2013 by Bill Reilly, who began developing revolutionary ammunition technology in his basement laboratory in Clearfield, Utah starting in 2010.

Reilly's passion for shooting drove him to create ammunition that would allow enthusiasts to shoot more by removing the traditional restraints of lead-based projectiles.

The company officially launched in 2013 with a team of experts in firearms, physics, chemistry, material sciences, and production processes.

SIM-X has revolutionized the ammunition industry by creating the first truly lightweight, high-velocity, lead-free ammunition using their patented SUBMASS technology.

Today, the Utah-based company serves recreational shooters, law enforcement agencies, and military personnel with innovative ammunition solutions that deliver superior performance while maintaining environmental safety.
