Buffalo Bore Heavy Strictly Business .357 SIG ammunition (brand part no. 25B20) loads a 125-grain full metal jacket flat nose bullet at genuine full power, built for shooters who want the cartridge running at its real potential. Buffalo Bore does not water this load down the way some factory .357 SIG ammunition does, keeping the cartridge’s signature velocity intact. The powder is flash-suppressed, giving the shooter a real tactical edge when the gun goes off in low light. In handgun ammunition for shooters who chose .357 SIG for its velocity, this is a load that does not compromise on it.
