A new special solution is given to the complete problem of Gun Internal Ballistics, of which Pidducks 1922 special solution to Lagranges Ballistic Problem is a simple special case. The solution is special in the sense that it is a similarity solution, in which the essential space-variable is separated from the time variable, and so it is derived by solving ordinary rather than partial differential equations. The restrictive assumptions on which the new solution is based are very few indeed. There are three scale-factors and seven modelling parameters in the general solution obtained, and two numerical examples are given for widely differing families of Internal Ballistics, which illustrate the salient features of the solution.
