Since the beginning of time, man has sought out weapons for protection and for attack. Guns were a far leap past the knives and arrows that preceded them. Just as with any other contest, as guns were used the race was on for more and more powerful guns. This is a compilation of the ten most powerful guns man has ever made. They are from different countries and developed at different times in history, most for a specific purpose or need as dictated by the period of time. Each has its use and each is unique in its own way.
