The Buffalo Bore Buffalo-Barnes Tactical .357 Magnum 140gr Barnes XPB Lead-Free is a 20-round box of low-flash, short-barrel .357 Magnum ammunition (Buffalo Bore part no. 19I20). It uses an all-copper, lead-free 140-grain Barnes XPB bullet rated at 1,150 fps. Buffalo Bore expects roughly 22-plus inches of penetration in flesh and bone and a mushroom of roughly .55 caliber. The load produces less felt recoil and blast than its Heavy .357 Magnum load, so it suits lightweight short-barrel revolvers. It is still a full-power .357 Magnum load.
