The THDA(R) is the perfect cartridge for home defense and law enforcement professionals operating in crowded urban environments. THD (Tactical Home Defense) produces extensive damage in the first block of ballistic gelatin, expending virtually all of its devastating energy within the first 13″. Controlled penetration (only 2″ in the second gelatin block) limits liability on unintended targets. It offers more than enough stopping power (even against criminals wearing bulletproof vests), but because the wad is designed not to separate from the slug, risk to innocent bystanders is reduced. The lower recoil allows fast followup shots in case of a multiple-target scenario. The THD is the best safeguard for you and the ones you love. Order today!
