Frangible bullets may represent an unconventional threat to personal body armor, when contrasted with traditional lead based bullets. Results of own shooting experiments confirm that the wound potential of bullet can be changed in a very large extent with the change of the manufacturing technology and the bullets geometry. Frangible Flat Point [1000 count]] NOT LOADED AMMUNITION. Yes, their obvious use is for close-quarters training, but theyre undeniably solid choices for hunting and self-defense. Another desirable characteristic of Frangibles for Concealed Carry and other uses is the absence of exit wounds, which greatly reduces the risk of unintentional injuries and collateral . Frangible bullets penetrate less than non-frangible bullets because after the bullet comes apart, the resulting individual fragments have less weight and therefore less momentum (energy) to drive them through a medium.
