SMOKELESS POWDER RESULTS. THE SPOTS REPRE¬ 
SENT THE INDIVIDUAL READINGS. 
Thirty other rounds were fired with black powder, and 
only one shot was markedly irregular. On the other 
hand, the cartridges referred to were not all loaded at 
the same time, and one series of five rounds showed 
results not in accordance with those of the other twenty- 
five cartridges. This dissimilarity was confirmed by the 
recoil, which was carefully measured to test general be¬ 
havior. The figures for the particular results which are 
depicted in the two diagrams above, are now set out in 
tabular form, as also is the method of correcting the 
figures in accordance with the new rule. It will be 
seen with black powder that the over-registration due 
to the use of overlong crushers has been absolutely 
corrected, so that the three sets of pressure have been 
brought to an absolute equality, the latter of course, 
being a mere coincidence. The smokeless powder re¬ 
sults, due to the irregularities already' noticed, do not 
work out quite so nicely on the face of things. Though 
the correction appears to be slightly overdone in the 
first example, the sound explanation is that the pressures 
did really vary in the manner shown. Another set of 
smokeless powder results has been appended, in which 
the variation happened to be the other way round. The 
many results which have been taken, in addition to 
those here published, confirm the general applicability 
of the proposed rule to all practical conditions. The 
figures referred to are now given: 
Pressure results to test the effect of using different 
lengths of copper crushers, _ and the treatment proposed 
for correcting the Over-registration which ensues. All 
measurements in inches:
