Krupp gun. Steel shell. 
It will be observed that in the first instance the practice was in favour of 
the Woolwich gun. This advantage was attributed by the Prussian Artillery 
Committee to the use of an inferior powder in the Krupp gun. On the 
second occasion, the advantage was in favour of the Krupp gun firing 
steel shell—to an extent, however, which is inconsiderable, but which it 
is not difficult to explain. It may have been due, for example, in a great 
degree, to the more accurate make and homogeneity of the carefully tooled 
steel shell, as compared with the relatively rude cast-iron chilled projectiles; 
and it may probably in part be accounted for by the greater uniformity of 
the prismatic powder—a uniformity which Captain von Doppelmair admits,
