ARMOUR-PIERCING PROJECTILES.

1. Shells with pointed heads . Tlie results obtained with these, with 
a charge of 30*6 lbs., corresponding to a range of 3032*6 yds., are 
shown in table. In continuation of the trial with these, and a charge 
of 33*8 lbs. corresponding to a range of 2302*7 yds., the following 
results were obtained :— 
Those projectiles of Nobel, chilled over their entire surface, perforated 
the plate and backing, but broke up, and the pieces were found 
467 yds. behind the target. 
Cast-iron projectiles of the same factory with chilled heads perforated 
the target, and were found 583 yds. in rear. Pieces were broken from 
the body of these shells without the inner cavity being broken into.

The steel shell of Futilofslcy gave the same results as the chilled 
shells, i.e.j they perforated the target and were found broken up 
233 yds. behind it. 
The Terre-Noire shells perforated the target and were found entire 
467 yds. behind it. The heads were slightly deformed. 
2 . Shot with pointed head, and shells. Four shot were fired with a 
charge of 30*6 lbs., and having an equal energy to that of the shells 
of the above series. The factory of Putilofsky made two of these 
shot from Martin steel, whilst the Nobel factory made the other two of 
chilled iron, having different degrees of hardness. One of the two 
first mentioned shot perforated the plate and stuck in the backing 
apparently entire, except that a small piece was broken off the base; 
the depth of indent was 24*9 ins. The second shot in passing through 
the backing turned towards the side, and the head and part of the 
body stuck in the backing. The base rebounded in pieces.
