Abstract. The Finnish defense Forces have implemented a surveillance system for
gun propeling charges utilizing conscript practice troop firings. In this
study the muzzle velocity data collected during troop firings of
a 155-mm weapon system have been statistically evaluated. The elimination
of the first round fired of each series of collected
muzzle velocity data was found to reduce the variation in
the data. For one charge zone, the study determined a
need to verify the validity of standard muzzle velocity values
in the firing tables. The muzzle velocity data collected in
conscript troop firings were found to be suitable for the
estimation of lot-to-lot and gun-to-gun variances if the data is
not too unbalanced. The methodology for identifying and removing erroneously
marked observations and outliers in the muzzle velocity data collected
by conscripts has been developed and the evaluation of the
results connected to each studied charge lot/zone has been conducted.
The muzzle velocity data collected was found to be usable
for numerous purposes, as long as the characteristics of the
data are taken into consideration.
