Owner of Buffalo Bore Tim Sundles on 380 Ammunition:
The 380 auto inhabits a valuable and useful place in our society, mostly because of the easily concealable, tiny pistols chambered for it. HOWEVER, because of the very limited size of the cartridge, it is plagued with limited power and therefore most of the existing ammo in 380 auto suffers from not being reliable as a man-stopper. We've studied and played with nearly all of the existing available 380 ammo and find it wanting as a reliable means of self defense.
Item 27F/20 is the very same load as 27E but, it uses a 95 gr. FMJ-FN (Full metal jacket-flat nose) bullet. We designed it for folks who simply don't like hard cast bullets. Although it is 5 grains lighter, it is moving a tad bit slower than the 100gr. hard cast bullet. This is because the hard cast bullet produces less friction in the barrel than a jacketed bullet and therefore produces less pressure, so we can run it a little faster even though it is heavier. Some pistols may not give good accuracy with the cast bullet, and some folks don't like cast bullets, so we made the same load with a jacketed bullet for those folks. This FMJ-FN load is designed to do the very same thing as the hard cast load above. Check out my "real world" velocities from my "real world" pistols below. You can expect nearly 20 inches of straight-line penetration with this load.
