20 cartridges per box Large game handgun hunters compare the Federal Vital-Shok to your current ammunition and see the difference. The 140-grain Barnes Expander bullet is made entirely out of copper with a hollow cavity construction for consistent expansion and bullet weight retention. Coming out of the muzzle at a whopping 1800 feet per second, the Vital-Shok has enough energy transference to bring down the largest buck. Compare and then conduct your own shooting test and you will choose Federal for your next hunt. Mfg: Federal See Item Details Below
