The Buffalo Bore Penetrator 9mm +P+ 124-grain Full Metal Jacket Flat Nose (Buffalo Bore part no. 24F20) is loaded to the pressures serious shooters expect from this small Montana company, not the watered-down velocities of mass-market factory ammo. This round is a Penetrator-profile loading engineered to feed reliably through subguns and carbines while punching through intermediate barriers, built around a full-metal-jacket flat nose that feeds reliably and drives straight through without expanding. Buffalo Bore hand-inspects every batch and loads with quality brass cases and clean-burning powder to keep pressures consistent from box to box. It’s a strong choice for shooters who carry, hunt, or train with 9mm +P+ and want a load that actually performs at the pressures printed on the box.

Key Specifications

• It’s chambered in 9mm +P+, so it runs in any firearm built for the standard factory cartridge.
• The 124-grain bullet weight sits toward the lighter end for the caliber, which shapes both recoil and penetration depth.
• The bullet is FMJ-FN construction: it’s a full-metal-jacket flat nose that feeds reliably and drives straight through without expanding, and holds its shape and drives straight through rather than expanding.
• This is a Penetrator-profile loading engineered to feed reliably through subguns and carbines while punching through intermediate barriers.
• Cases are brass, which reloaders can resize and reuse, and which feeds reliably in both revolvers and lever guns.
• It ships 20 rounds to a box, sized for range trips and practical carry rotation.
• A full case runs 12 boxes (240 rounds), the volume option for shooters who train or carry this load regularly.
• Buffalo Bore’s box price works out to about $1.55 per round, in line with other premium hard-use ammunition.
• Buffalo Bore loads and pressure-tests every batch in-house in Montana rather than outsourcing to a mass contract loader, which is why the velocities hold consistent box to box.
