After a great deal of discussion and correspondence with Vannevar Bush, the committee developed the following course of research:

1. Comparative studies of different propellants with the same gun and projectile, the weight of charge being varied and the muzzle velocity of projectile held at the same high value.

2. Studies of dependence of erosion on the chamber volume and shape for a given propellant, the weight of charge being varied to produce constant muzzle velocity.

3. The development and testing of accelerated methods of comparing erosive powers of propellants; these studies to be carried out at first on existent propellants, including the standard American service powders and available foreign powders, and later on new powders developed under the NDRC program.

The committee intended to contract research teams and manufacturers to develop the appropriate instruments for measuring propellant attributes, after which it would then embark on a comprehensive study of powders used by both Allied and Axis forces. This data in hand, the committee would then recommend future courses of study into propellant manufacturing.
