The Buffalo Bore 27E20 standard pressure load approaches .380 ACP with old-school reliability and real-world performance. Built with a 100 grain hard cast flat nose bullet seated in boxer-primed brass, this is ammunition designed to work when it matters most.
The flat nose design is the key to what makes this round effective in such a compact caliber. Unlike traditional round nose bullets that tend to slip and slide through material, the flat profile cuts and crushes its way forward. You get predictable, straight-line penetration that rivals much larger calibers. The hard cast construction won't deform on impact, which means you get deep, consistent performance that doesn't rely on expansion to be effective.
Buffalo Bore loaded these with flash suppressed powder because the reality is that most defensive situations happen in low light or darkness. The last thing you need is your own muzzle flash blinding you during a critical moment. This attention to detail separates thoughtfully engineered ammunition from generic factory loads.
These aren't lab numbers from artificially long test barrels. Buffalo Bore chrono tests from actual pocket pistols and compact .380s to give you honest velocity figures. You're looking at 975 fps from standard pressure, which delivers 211 ft-lbs of muzzle energy. That translates to roughly 20+ inches of straight-line penetration in tissue and bone. Reloadable brass cases make practice and training affordable too.
Yes. Buffalo Bore chronographs these loads in real pocket .380s and compact models to verify they function reliably. You'll see lower velocities from shorter barrels (around 910-950 fps from sub-3 inch barrels) compared to full-size pistols, but feeding and cycling remain solid. Just verify your pistol is in proper working condition before using any defensive ammunition.
The 27E20 is standard pressure, designed for broad compatibility across all .380 platforms. It still delivers impressive penetration and velocity for the caliber. The +P versions load hotter (around 1,150 fps) for maximum performance, but the standard pressure 27E20 is a solid choice if your pistol manufacturer recommends against +P ammunition.
Hard cast bullets don't damage barrels any more than copper-jacketed rounds do. The flat nose profile and hard construction actually protect your bore better than soft lead since there's minimal leading. Many shooters using Buffalo Bore hard cast loads report excellent longevity with their firearms.
Hard cast flat nose delivers deep, reliable penetration through barriers and bone that hollow points sometimes fail to achieve in the low-velocity .380. The flat nose increases tissue damage compared to round nose bullets. If your priority is deep, consistent performance through clothing and barriers, hard cast performs where expansion-reliant designs might disappoint in the .380 caliber.
