Formulation of Gun Propellants

1) The ballistic requirements of a gun, that is, muzzle velocity (Vp) and pressure 

2) Gun characteristics viz caliber or bore diameter, shot travel or barrel length, effective chamber capacity and ballistic efficiency of the gun (%). 

On basis of the above data, the force constant (Fj for propellants is arrived at by using Equations (4.15) and (4.16) 

A large number of formulations are available for use the formulation is decided and tailored depending on the requirements of users. However, no single formulation meets all requirements of the user. An ideal gun propellant should possess most of the following properties.
