Lever is obtained as which is the mechanical advantage of the lever. This equation shows that if the distance "a" from the fulcrum to the point "A" where the input force is applied is greater than the distance "b" from fulcrum to the point "B" where the output force is applied, then the lever amplifies the input force. If the opposite is true that the distance from the fulcrum to the input point "A" is less than from the fulcrum to the output point "B", then the lever reduces the magnitude of the input force.

Lever action the development of its popular hammerless Models 1895 and 1899 (which became named the Model 99) lever-action sporting rifles. The Models 1899/99 were produced from introduction in 1899 until the expense of producing the rifle, and declining interest in lever-action rifles from the 1950s on, resulted in dropping the Model 99 from production in 2000. Unlike most Winchester and the Marlin lever-action rifles, which used a tubular magazine requiring round-nose or flat-nose bullets, Arthur Savage designed his rifle using a rotary magazine. This allowed the 99 to use cartridges with spitzer pointed bullets for increased ballistic performance. The 99 was
