Invented by Randy Cooling, the Safari Tuff Cooling Brass Insert is a first of it's kind. It allows for 3 different weight options. 100 grains unbroken, 75 grains or 50 grains. Simply grab the section you want to break off with a pair of pliers and hold the remaining insert with another pair of pliers. Gently break so as to not bend the insert.
