A continuous process for propellant production in the modernization program and the need for rapid ballistic assessment of propellant prompted the US Army to authorize a three year acronym AUTOCAP, to improve and automate the current procedure for accepting propellant. A major sub-task of this development program was the automation of the conventional closed bomb. Steps taken to accomplish this sub-task consisted of 1 a review of all closed bomb data acquisition and analysis procedures at military installations and 2 assessment of the ability of these closed bomb methods to predict actual gun performance. Towards this end, data from 14 special AUTOCAP single base M1 propellant lots was analyzed using the standard analysis specified in MIL-STD- 286B, 801.1 i.e. Relative Quickness RQ and Relative Force RF, as well as several new computerized techniques. RQ varied in these special lots from 72 to 121. In this report the influence of numerical methods on data is shown and comparisons are made between predicted and actual ballistic behavior.
