Byrna Technologies HD Projectiles Features The Byrna Technologies HD Projectiles deliver their payload through a .68 caliber projectile designed to work with Byrna s line of less lethal launchers. Each projectile carries a blend of Oleoresin Capsicum and PAVA pairing two distinct pepper irritant compounds rather than relying on a single agent. Combining OC and PAVA increases the overall potency of the payload giving the user a stronger deterrent effect on impact. This dual-compound approach is part of what makes the HD Series stand out among less lethal ammunition options. The projectiles ship in a 25-count tub giving the user enough rounds to train practice and still keep a reserve loaded for defensive use. Packaged as accessory ammunition rather than a firearm cartridge they are meant to be paired with a Byrna launcher as part of a complete less lethal defense system. The compact tub packaging keeps the projectiles organized and easy to store near a home defense launcher or in a range bag. The Byrna Technologies HD Projectiles in .68 caliber give users a dedicated purpose built option for practicing with and deploying their less lethal launcher.
