The Buffalo Bore 10mm Auto 180-grain JHP is a full-power self-defense load built to SAAMI maximum specifications. This ammunition pushes a 180-grain jacketed hollow point to 1350 feet per second from a 5-inch barrel, producing 728 foot-pounds of energy at the muzzle. Buffalo Bore loads 10mm ammunition to the cartridge’s original ballistic standard — the performance level adopted by the FBI before industry-wide downloads became common. For shooters who carry 10mm pistols for backcountry defense or personal protection, this load delivers the velocity and energy the cartridge was designed to produce.
Performance at a Glance
Buffalo Bore manufactures this ammunition using flash-suppressed powders to preserve night vision in low-light defensive scenarios. Each round is loaded in reloadable boxer-primed brass with non-corrosive primers. The 180-grain jacketed hollow point is designed for controlled expansion at full-power velocities. Buffalo Bore cautions that this ammunition is intended for modern firearms only — older 10mm pistols manufactured before 1990 may not be rated for SAAMI-maximum pressures. Check your firearm’s manual or contact the manufacturer before firing any full-power 10mm load. In autoloading pistols, Buffalo Bore notes that a heavier recoil spring may be required to prevent premature breech opening and maintain consistent velocity spreads under 50 fps. This is a tuning consideration for precision work — the ammunition functions reliably in all modern 10mm pistols in serviceable condition, regardless of spring weight.
