HAIL OF BULLETS.
Machine guns form a very important
part of a vessels armament. These
destructive implements can be worked
so fast that they throw perfect hail
of bullets on the object against which
they are aimed. The Colt rapid.fire
gun has been mounted on several of
the boats of the mosquito fleet. This
gun is of millimeter calibre, which,
according to the way the size Of guns
are calculated here, is equal to .236
calibre, or the same size as the rifle
now used by the navy. This gun Can
fire 200 shots minute, and has
range of 5000 feet. The metal in the
barrel of the gun is inch thick, and
the cartridges are fed from belt, con-
tanning 1000 stored in a steel box at.
tached near the breech. AT test
made in the navy yard bullet from
one of these guns was sent through
three-eighths-inch steel plate, through
20 inches of wood, through steam
coil, and finally through another one
eighth-inch steel plate. The gun
weighs SO pounds and the tripod SO
pounds.
Hotchkiss guns are divided into two
classes, rapid fire and machine. The
machine guns throw projectiles one
and three pounds respectively. The
greatest range of three-pounder is
mile and half and of a one-pounder
about a mile. There are one, three
and six pound rapid fire guns, which
are largely used on all the vessels in
the navy.
There are two kinds of one-pound-
ers, light and heavy. The light gun
weighs 70 pounds and is 33 inches in
length. The projectile weighs one
pound, and to fire it requires 2.S
ounces of black powder or 81 ounces
of smokeless powder. The range Of
these guns is about mile, and they
are little more destructive when the
smokeless powder is used. With black
powder the initial velocity, or speed
at which the projectile leaves the muz.
zle, is equal to 1878 feet second, and
the muzzle energy is equal to the sud-
den impact Of 1874 tons. Immediately
after leaving the muzzle one OF these
shots would penetrate IL inch of steel,
at a distance of 1000 yards it would
penetrate half an inch and at 1000
yards it would penetrate fraction
over third of an inch.
With smokeless powder the initial
velocity is equal to 1909 feet second,
the muzzle energy is equal to 15.9 tons
and the perforation is an inch aud a
half at the muzzle, 0.55 inch at l. 900
yards and O.39 inch at 1000 yards.
POWER OF oNE.PoUNDERs.
The heavy 1-pounder weighs 120
pounds, is IS inches in length, but
only throws projectile weighing one
pound little over mile. 1t takes a
charge of ounces of black powder,
and the initial velocity is 1900 feet,
the muzzle energy is 22.4 tons and its
perforation is LAS inches at the muz-
zle, two-thirds of an inch at 1000
yards, and half an inch at 1900 yards.
A 3-pounder weighs 4S4 pounds, is
80 inches in length, and throws pro.
jectile weighing three and a third
pounds. This gun, like the l-pound-
er. can be fired with black or smoke
less powder, but is most effective when
smokeless powder is used. With black
powder the charge is % ounces, the
initial velocity at the rate of 2,OOO
feet second, and the muzzIe energy
equal to 90 tons. Its power of per-
foration is Al inches at the muzzle, 2
inches at 1000 yards, and l.2 inches
at 1000 yards.
When smokeless powder is used the
charge weighs only Is ounces, and the
muzzle velocity is equal to 1852 feet
second. The muzzle energy is 12S
tons, and its perforation SIS inches at
the muzzle, 81 inches at 1000 yards
and is inches at 1000 yards. These
guns will carry about a mile and a
half
The six-pounder, as its name de-
notes, will throw a projectile weighing
six pounds, and it will carry about
three miles. The gun itself weighs
sos pounds, and is 9 feet 9 inches in
length. The charge of powder it takes
is two pounds, and the shot leaves the
muzzle at the rate of 1870 feet sec
ond. The energy of this shot at the
muzzle is equal to 145 tons. AT the
muzzle it will penetrate 81 inches at
900 yards it will penetrate 81 inches,
and at 1000 yards 81 inches. |
The marines on the ships are armed
with very powerful rifle called the
Lee straight-pull rifle. This is mag
azine gun Of 1856 calibre and it uses
smokeless powder in its cartridges
and steel pocketed bullet. The ini-
tial velocity of this bullet is equal to
2,46O feet a second. 1t will penetrate
81 inches of dry pine wood 10 feet
from the muzzle of the guns and it will
kill at more than a mile. The press
ure on the gnn when fired is 10000 to
the square inch. Forty-five shots
minute can be fired with it.-New
