The Buffalo Bore Ammunition Heavy Strictly Business 357 Sig round is purpose-built for shooters who demand terminal performance in a compact, potent cartridge. Loaded with a 125-grain jacketed hollow point, this is serious defensive ammunition for those who've chosen the 357 Sig for its flat trajectory, fast velocity, and proven stopping power in a duty or carry pistol. Buffalo Bore has built a reputation on pushing handgun ammunition beyond standard performance, and this load reflects that commitment to ballistic effectiveness without compromising reliability.
The 357 Sig sits in a narrow lane between 9mm and .40 S&W — faster than both, with the sectional density to drive deep while the hollow point expands reliably across a wide range of velocities. Whether you're running this through a full-size duty pistol, a compact carry gun, or practicing on the range, Buffalo Bore's quality control and consistent powder charges mean you'll get uniform point-of-aim shot to shot. The jacketed construction resists barrel fouling, and the ammunition comes packaged 20 rounds per box with a 12-box case quantity for serious shooters or departments stocking up.
If you've invested in a 357 Sig platform, you know ammunition selection matters. Buffalo Bore's Heavy Strictly Business load respects the cartridge's potential and delivers the kind of round that makes sense for those who carry for a living or take personal protection seriously.
