Buffalo Bore Ammunition 25B20 Heavy Strickly Business 357 Sig 125 gr Full Metal Jacket Flat Nose (FMJFN) 20 Per Box/ 12 Cs
Buffalo Bore Ammunition's Heavy Strictly Business 357 Sig load delivers serious stopping power in a proven self-defense round. Built on the reputation Buffalo Bore earned pushing the boundaries of handgun ballistics, this 125-grain full metal jacket flat nose (FMJFN) round is engineered for shooters who demand more from their carry ammunition. The 357 Sig cartridge has earned respect in law enforcement and defensive circles for its velocity, penetration, and flat-shooting trajectory, and Buffalo Bore's heavy loading maximizes those advantages.
The flat nose profile typical of Buffalo Bore's strictly business ammunition serves a dual purpose: it enhances feeding reliability in semi-automatic platforms and provides a wider wound channel than traditional round-nose designs. This isn't range plinking ammo—it's ammunition built with a specific defensive or duty purpose in mind. The full metal jacket construction ensures controlled penetration and consistent performance through various barriers, a consideration that matters if you trust this round to protect you or your family.
Each box contains 20 rounds, with cases available in 12-box quantities for those who shoot regularly and want to stock up on a load they trust. Buffalo Bore ammunition carries the credibility of a manufacturer that refuses to cut corners on velocity, consistency, or quality control—they've built their reputation by refusing to participate in the race to the bottom that defines so much of the ammunition market.
