Buffalo Bore Dangerous Game 10mm Auto Ammo 190 Grain Lehigh Solid Wide Flat Nose Lead Free Box of 20

When you’re hunting hogs at spitting distance or banking on your sidearm as backup in bear country, Buffalo Bore Dangerous Game 10mm Auto ammo delivers the penetration you need without the smear. This 190-grain Lehigh solid wide flat nose is a mono-metal projectile — brass or copper alloy, depending on the batch — that holds its profile through heavy bone, maintaining a wide flat meplat for maximum wound channel diameter. At 1200 feet per second and 607 foot-pounds of energy from a 5-inch barrel, the round sits in the sweet spot between controllability and terminal performance. The 10mm Auto cartridge was built for this kind of work, and Buffalo Bore’s dangerous game line leans into that legacy with non-expanding solids that prioritize depth over expansion.

Performance at a Glance

Buffalo Bore loads these rounds in Montana, using boxer-primed brass cases and powders selected for clean ignition and consistent pressure curves. The Lehigh wide flat nose is a monolithic solid — no jacket to separate, no core to fragment. The flat nose measures wider than most hard-cast equivalents, which translates to a larger permanent crush cavity as the bullet tracks through tissue. Mono-metal bullets are lighter for their length than lead-core projectiles, so a 190-grain solid occupies more case volume than a 190-grain hard-cast bullet. Buffalo Bore accounts for this in their powder charge, balancing pressure and velocity to stay within SAAMI specs while maximizing energy transfer. The lead-free construction keeps your barrel cleaner and eliminates the nose smearing that can occur when hard-cast bullets strike large bones at high velocity. Brass cases are reloadable, and the boxer primers accept standard large pistol primers for handloaders looking to duplicate the load or work up a tailored charge.

Specs at a Glance

This load is built for hunters who carry a 10mm as a primary or backup firearm in environments where large, dangerous game is a possibility. If you’re running a Buffalo Bore 10mm ammo rotation, this dangerous game variant complements expanding hollow points by offering maximum penetration when bone and muscle mass demand it.

Who It’s For

You carry a Glock 20, a 1911 in 10mm, or a Smith & Wesson 610 revolver. You hunt feral hogs in heavy brush, you guide clients in brown bear territory, or you want a woods-carry load that won’t quit after hitting the shoulder blade of a 300-pound animal. This round is for handgun hunters who prioritize depth over expansion, who understand that a wide flat nose creates its own wound channel without relying on petal expansion, and who accept the trade-off of mono-metal cost for cleaner ignition and consistent terminal performance. If you’re reloading, the once-fired brass is high-quality stock for developing your own loads. If you’re hunting in lead-free jurisdictions, this round meets those requirements while delivering the energy profile the 10mm Auto was designed to provide.
