T4E PB cal. .43 10-gauge pepperballs contain synthetic pepper powder that effectively marks and incapacitates an attacker when released.
The 0.54 gram pepper bullets can be used in all .43 caliber T4E training pistols and carbines. The hard shell of the bullets breaks only after hitting an attacker or hard surface releasing a cloud of synthetic pepper powder with a very high SHU.
The powder instantly penetrates the respiratory tract and eyes, so that the attacker is effectively incapacitated almost immediately upon hitting or coming into range of the gas cloud and is incapable of taking coordinated action.
