Owner of Buffalo Bore Tim Sundles on Buffalo Bore Heavy 357 Sig Low Flash Ammunition:
Because you requested it, Buffalo Bore is now producing two full power 357 Sig. loads. These loads are full power 357 Sig. Not the watered down stuff that other factories are already producing. Why is it that a new cartridge gets developed with touted ballistics in the media, only to have the ammo manufacturers "water" it down after a few years on the market? (The same thing happened with the original 10MM) The 357 Sig. was designed to blast a 125gr. bullet at 1,425 FPS out of a four inch carry gun barrel. (Not a much longer test barrel) So, that is what both our loadings do.
We use flash suppressed powder so that you wont be blinded by your own gun fire should you be required to drop the hammer in low light. Since over 90% of shootings in America happen in low light, flash suppressed ammunition is a huge tactical advantage.
Item 25A utilizes the 125gr. Jacketed Hollow Point bullet. It is designed to open radically and penetrate roughly 12 to 14 inches in tissue. Note my velocities from my real world pistol, (not a test barrel) below.
a. Sig. Mod. 229, 4 inch barrel - 1,430 fps (567 ft. lbs.)
