ion of the obvious primary
necessity for the attainment of those qualities. We find, however, that
our progress towards perfection in this direction cannot proceed beyond
a certain point, except at the cost of other qualities, which cannot be
sacrificed with impunity.
Regarding it as a settled point that any recoil of the gun is just so
much taken from the initial velocity of the ball, (and if any one doubts
it, let him try the experiment of throwing a stone, and stepping
backwards at the moment of propulsion,) it is obvious, that, for the
attainment of the longest range, such a preponderance of weight in the
gun over that of the projectile is necessary as to secure the least
possible recoil, and this point seems to have been fixed by our best
gun-makers at the ratio of five hundred to one, which would require a
gun weighing nearly sixteen pounds to carry a half-ounce ball or shot.
We use the word _ball_ from habit, meaning, merely, the projectile,
which will probably never again resume its spherical shape in actual
service. We conceive the perfection of precision and range in
rifle-practice to have been attained in the American target-ride,
carrying a slug or cone of one ounce weight,--the gun itself weighing
not less than thirty pounds,--and provided with a telescope-sight, and
Clark's patent muzzle. At three-quarters of a mile this weapon may be
said to be entirely trustworthy for an object of the size of a man, and
to have force enough at that distance to disable three men. But it is
obvious that such weight and such equipments as are required for it must
render it utterly useless for ordinary field-service. It becomes, in
fact, a species of light artillery, and as such we are firm in the
conviction that it is destined to establish for itself a reputation
which will render it henceforth a necessity in the composition of an
army.
For troops of the line the weight of the gun should not exceed ten
pounds. Now, if we reduce the rifle to that weight, and preserve the
ratio of 1-500 as that of the ball, we reduce its range; for the
momentum being, as every school-boy knows, in proportion to weight as
well as velocity, a projectile which may be perfectly sure for two or
three hundred yards flies wide of the mark at six hundred, and can
hardly be found at a thousand. Here begins the operation of the sliding
scale, in the necessity of sacrificing some degree of precision, in
order to procure a weapon fulfilling other ind
