Due to the light weight of the shot material, it should be used at distances of not less than 20 yards or more than 50 yards from your target. Perfect for home defense or animal control where you are looking for less than lethal. We have brought rock salt to a whole new level by combining our Israeli Police pepper compound with the rock salt. 5 Round Pack, 2 3/4" Round.
