Some really interesting training ammunition here from Ultimate Training Munitions. Initially, I didn’t understand the purpose of the “Silent Blank Round” since it generates no noise and no projectile, but, as Bob states, it’s perfect for dry-fire drills because it cycles the action for you. To dry-fire most guns, you must manually cycle the action after every pull of the trigger, which can create a training scar.
Wonder if any of these will be available to us civilians?
