Manual of Military Training Part 107

(d) After the leather has been allowed to become partially dry, it should be rubbed vigorously with a soft cloth to give it the neat, healthy appearance that is desired.

=1317. Oiling.= If the foregoing instructions have been carefully followed, the appearance should now be perfect, and if the leather is soft and pliable nothing further is required. It will be found, however, that it will be necessary from time to time to apply a little oil. It is not practicable, owing to different conditions of climate and service, to prescribe definitely the frequency of oiling. It has been found that during the first few months of use a set of new equipment should be given at least two applications of oil per month.

Thereafter it is entirely a matter of judgment, as indicated by the appearance and pliability of the leather. Frequent, light applications are of more value than infrequent heavy applications.

=1318. New equipment.= Before using, perfectly new equipment should in all cases be given a light application of neat's-foot oil; soap is unnecessary because the leather is clean. The application of oil is important because leather equipment frequently remains a considerable time in an a.r.s.enal or depot and in spite of periodical inspections and dubbing it is probably too dry for severe service.

=1319. How to apply oil.= The quant.i.ty of oil to be used can not be definitely prescribed. If not enough oil is used, the leather will be stiff and brittle; if too much is used, it will soil the clothing and acc.u.mulate dirt. The leather should, therefore, be saturated with sufficient oil to be soft and pliable without excess sufficient to cause it to exude.

In applying the oil the following general instructions should govern:

(a) The oil should be applied to the flesh side of the equipment where practicable when the leather is clean and still damp after was.h.i.+ng (about half dry), because it penetrates more uniformly when applied from the flesh side, and when the leather is damp. If the leather is dry it will absorb the oil like blotting paper, preventing proper distribution.

(b) The oil should be applied with an oiled rag or cotton waste by long, light, quick strokes--light strokes, so that the pressure applied may not squeeze out an excess of oil; quick strokes, so that the leather may not absorb an undue amount of oil. The endeavor should be to obtain a light, even distribution.

(c) After applying the oil the leather equipment should be allowed to stand for 24 hours, if practicable, in a warm dry place. It should then be rubbed with a dry cloth to remove any unabsorbed oil.

Points to Be Remembered

=1320.= Therefore, from what has been said, the following points must be remembered:

(a) Keep leather clean.

(b) Keep leather pliable by frequent applications of oil.

(c) Use only materials furnished by the Ordnance Department. _Shoe polishes_, etc., are almost invariably injurious.

(d) _Dry all leather wet from whatever cause, in the shade_; never in the sun or close to a steam radiator, furnace, or boiler.

(e) Leather should habitually be stored in a cool, dry place, _without artificial heat_.

FOOTNOTES:

[15] "Viscol" is the best oil for softening all kinds of leather that the author knows of. It is made by The Viscol Co, East Cambridge, Ma.s.s., and can be obtained from the post exchange.

[16] Propert's Harness Soap is excellent. However, since the European War its issue has been discontinued by the Ordnance Department.

"Viscol," obtainable from the post exchange, is the best oil for softening all kinds of leather that the author knows of.

CHAPTER XVIII

CARE AND DESCRIPTION OF THE RIFLE

Care

=1321. Importance.= The care of his rifle should be the soldier's first thought; for, if he would have it take care of him in time of danger, he must take care of it at all times.

_It is a generally recognized fact that more rifles become inaccurate and unserviceable by the lack of care than by firing._

The instructions for taking care of the rifle are few and simple.

Learn them well and _apply them constantly_--it only requires a little care and patience. You will be well repaid for it. It may some day save your life.

=1322. Care of bore requires work.= The bore of the rifle is manufactured with the greatest care in order that a high degree of accuracy may be obtained, and it should, therefore, be properly cared for.

The proper care of the bore requires conscientious, careful work, but it pays well in reduced labor of cleaning and in prolonged accuracy life of the rifle, and better results in target practice.

=1323. How to clean the bore.= With the cleaning rod the bore must always be cleaned from the breech--never from the muzzle. Cleaning from the muzzle is liable to wear and otherwise injure the mouth of the barrel, which is easily injured and thus the piece rendered inaccurate.

First, remove the bolt from the rifle, place the muzzle on the floor, a board, or piece of canvas, and do not remove it therefrom while the cleaning rod is in the bore. Never place the muzzle on the bare ground, lest dirt should get into it. (Note. Of course, if a rack is provided for cleaning rifles, it should be used instead of placing the muzzle on the floor.)

To clean the bore use patches of rag, preferably canton flannel, cutting them into squares of such size that they may easily run through the barrel.

=1324. What care of the bore consists of.= Briefly stated, the care of the bore consists of removing the fouling resulting from firing to obtain a chemically clean surface, and then coating this surface with a film of oil to prevent rusting.

=1325. Kinds of fouling.= The fouling which results from firing is of two kinds--the _powder fouling_, from the burning of the powder; and the _metal fouling_, from the nickel sc.r.a.ped off the bullet as it pa.s.ses through the bore.

The _powder fouling_ is highly corrosive, that is, it causes rust and eats into the metal, and it must, therefore, be removed as soon as possible.

The _metal fouling_ itself will not cause rust, but it may cover the powder fouling and thus prevent the cleaning material from getting at the powder fouling, which, as stated before, will eat into the metal.

When metal fouling acc.u.mulates in noticeable quant.i.ties it reduces the accuracy of the rifle.

=1326. How to remove powder fouling.= Powder fouling may be readily removed by scrubbing the bore with the soda solution (hot) furnished by the Ordnance Department, but this solution has no effect on the metal fouling.

It is, therefore, necessary to remove all metal fouling before we are sure that all powder fouling has been removed and that the bore may be safely oiled.

Ordinarily, after firing a barrel in good condition, the metal fouling is so slight as to be hardly perceptible, and is easily removed by solvents.

However, due to the acc.u.mulation of metal fouling, pitting (little hollows in the metal) or the presence of dust, or other abrasives (substances that cause the metal to wear away by rubbing), the fouling may occur in clearly visible flakes or patches and be much more difficult to remove.

=1327. How to remove metal fouling.= After scrubbing out the bore with the soda solution, plug it from the breech with a cork at the front end of the chamber or where the rifling begins.

Slip one of the 2-inch sections of rubber hose over the muzzle down to the sight and fill with the standard Ordnance Department solution to at least one-half inch above the muzzle of the barrel.

Let it stand for 30 minutes, then pour out the solution, remove the hose and breech plug, and swab out thoroughly with soda solution to neutralize and remove all trace of ammonia and powder fouling.

Wipe the barrel clean, dry, and oil.

With few exceptions, one application is sufficient, but if all fouling is not removed, repeat the operation.

Hoppe's Nitro Solvent No. 9 will accomplish the same result even better and quicker and with much less labor.

=1328. How to proceed in cleaning the bore.=

To clean the bore after firing, proceed as follows:
