Reduced Loads For Short Ranges
How To Reload High Velocity Cartridges With Small Charges Of Powder And Alloy Bullets For Lesser Game
by A.L. Bragg
PRACTICALLY every owner of a high-power rifle,
and those contemplating the purchase of one, have given more or
less thought to the problem of reloading high velocity cartridges
with small charges of powder and alloy bullets for short range
shooting. Every shooter recognizes the fact that modern metallic
ammunition is expensive and that the empty shell, which is an
article of mechanical perfection, is the most costly part of the
modern cartridge. It requires the very best materials and skilled
workmanship to manufacture a shell for a high-power rifle and it
seems wasteful to throw away every empty shell instead of using
them over and over again. The continued use of high velocity
ammunition, besides being expensive, shortens the life of the
rifle barrel and sooner or later the sportsman begins to consider
the problem of using a cheap and satisfactory short range load.
Reduced loads of certain brands of smokeless
powder and alloy bullets can be satisfactorily used in high-power
rifles. Black powder or semi-smokeless powders should not be used
in reduced loads because they are not intended for the modern
high-power rifle. Smokeless powders for high velocity loads will
not work satisfactorily when used in small quantities in large
cartridges, because they were designed to burn at the pressures
developed by the full charge loads. However, there is a class of
smokeless powders, like "Marksman" and "Unique," that are
manufactured especially for use in making up a short range load in
high-power rifles. Such powders burn very efficiently in rifle
shells having a large chamber space, developing a strong
propelling blast, without excess heat, and leaving no unburned
residue. Their proper use is not attended with any risk to either
the rifle or the shooter himself, and, if the reloading is
properly done, they will give good satisfaction in every way.
THE reloading of high-power rifle cartridges
with metal cased bullets and full charges of smokeless powder
should be done very carefully, for unless one thoroughly
understands the nature of the load he is using and is prepared to
do the work with the utmost accuracy, he may produce a load that
would bring disastrous results in the best steel rifle barrel
manufactured. The reloading of high velocity cartridges can best
be done by the cartridge companies where the work is done with
great accuracy and the cartridges are subjected to tests that
render them perfectly safe in properly constructed arms for which
they are intended.
Reduced loads for high-power rifles, as
described in this article, are not to be confused with the
so-called gallery loads, or loads limited to short range indoor
target work. A 30 caliber cartridge loaded with ten grains of
“Marksman” smokeless powder (which equals in volume almost 25
grains of bulk black powder) and an alloy bullet weighing from 125
to 150 grains, makes a cartridge suitable for shooting small or
medium sized game at ranges up to two or three hundred yards. The
velocity and accuracy of such a cartridge is surprising, besides
being such a pleasant and clean cartridge to shoot. Such a load
will group the bullets in an eight inch circle at two hundred
yards with the greatest regularity.
The first prerequisite towards reloading high
velocity cartridges with short range loads is to have clean, well
cared for shells. As soon as possible after firing, the primers
should be removed and the shells carefully washed with warm water
and soap, then rinsed in hot water. The shells can be placed in a
warm oven to dry, but they should not be allowed to become very
hot as it will anneal them. Shells that become soft are liable to
fit the rifle barrel too snugly, causing them to stick in the
chamber after firing. It is very annoying to be troubled with
empty shells sticking in the rifle chamber and failing to eject
properly, compelling the shooter to fall back on a cleaning rod or
other device to extract them. Shells should be elastic and springy
so that they will contract to some extent after firing and eject
easily. Heat softens brass. It cannot be hardened by sudden
cooling after being heated, as can be done with steel. Care should
be taken to see that the shells are clean and dry before putting
them away or reloading them, for the least bit of moisture or
dampness will cause corrosion of the inside of the brass case and
may cause deterioration of the powder charge in the loaded
cartridge. A corroded shell is almost worthless and a never ending
source of trouble. Rifle shells can be reloaded on an average of
about five to twenty-five times apiece, depending largely upon the
care they receive and the strength of charge that is used. The
writer has a number of shells that have been reloaded a much
greater number of times and they still show a good state of
preservation.
THE first step towards reloading a cartridge is
to seat a new primer in the pocket in the head of the shell. This
should be done with a recapping tool made especially for the
purpose so that the primer will be seated firmly in its place,
thus avoiding misfires or possibly accidents in the mechanism of
the gun. It is a very dangerous practice to seat a primer in a
shell containing powder, and one's safety demands that this work
be done while the shell is empty. After seating the primer, the
shell is ready for the powder.
There are three ways of measuring out the
correct amount of powder for the desired load; mechanical powder
measures, scales, and charge cups. The mechanical powder measure
is the most satisfactory way of measuring out the charge desired.
They can be easily and quickly set to throw any given charge with
accuracy and regularity. Accurate and finely adjusted scales of
the beam balance type and grain weights, make a very dependable
apparatus to weigh out smokeless powder charges, but they require
some patience and their slowness, when it comes to weighing out a
large number of charges, makes the weighing process the least
desirable of the three. The charge cup is a very handy and cheap
powder measure that will do the work very well where a machine to
do the work cannot be afforded, or one does not care 'to bother
with weighing out each charge separately. A charge cup holding 25
grains of black powder will hold approximately 10 3/4 grains of
"Marksman" and if the measure is filled exactly the same each
time, without jarring, it will serve the purpose very well.
Exactly the same amount of powder should be
used in every short range load if uniform results are to be
expected. Powder charges of 10 to 12 grains weight of "Marksman"
or corresponding loads of "Unique" can be used with alloy bullets
in 30 caliber rifles, 10 grains weight in high-power rifles of the
25 caliber class, and about 8 grains in high-power rifles using
bullets of a smaller diameter. Slightly heavier charges of powder
than those given can be used in each class, but as the amounts
named give all the powder needed for their particular use, there
is no need in getting closer to the point where there is liable to
be fusion of the base of the bullet.
Too much powder in a reduced load in a
high-power cartridge will cause the base of the bullet to melt,
resulting in a leaded barrel and a wild-shooting bullet. Bulk for
bulk, practically none of the many brands of smokeless powder will
weigh exactly the same, nor will ten grains of one powder equal
the shooting strength of another of the same weight. Every can of
smokeless powder gives the amount that should be used with any
particular load, and this limit should never be overstepped. Stick
to the brand of powder that suits your particular purpose best,
learn all its peculiarities, and then most of your powder troubles
will vanish.
FITTING the bullet into the mouth of the shell is a more painstaking piece of work than many would imagine. A brass shell cannot be heavily crimped into a hard metal bullet, nor can a shell be resized with a bullet in the mouth of it without deforming the bullet. In black powder shells, where the powder charge fills the shell, crimping is a comparatively easy matter as all that is necessary is to crimp the shell in front of the forward band on the bullet and the pressure of the powder against the base of the bullet will keep it in the desired position.
In smokeless powder cartridges the charge of
powder does not fill the shell and some means must be taken to
prevent the bullet from sliding back into the enlarged chamber of
the shell, as will sometimes happen with bullets in the short
range loads. As alloy bullets are, as a rule, slightly larger in
diameter than the metal-cased bullets in order to shut off all
escape of gas, they may fit tight enough in the shells so that the
cartridges can be handled without danger of the bullets receding
in the shells.
Where the bullets do not fit snugly in the
mouth of the shell and when the mechanism of the rifle demands a
tight fitting bullet, as in a tubular magazine gun, there are four
ways of making the bullet stay in the mouth of the shell where it
belongs. These ways are: using grooved shells, making indentations
in the shells, crimping the shell slightly into the forward groove
on the bullet and resizing the shell so that the bullet will fit
tightly. Grooved shells, having a groove around the shell for the
base of the bullet to rest against, are obtained of the cartridge
companies. Sometimes these shells cause trouble in some arms after
being used several times on account of the shell lengthening out
as the groove in the shell straightens. Slight indentations can be
made in the shells to prevent the bullets from receding by using
what is called a "shell indentor" which will make slight
indentations in the shells for the base of the bullet to rest
against when placed in the mouth of the shell.
By using a reloading tool having a crimping
shoulder, the shell can be slightly crimped into the forward
groove on the bullet, which will hold the bullet in place and
prevent it from receding or working loose and getting out of the
shell. Bullets can be held tightly in place in a shell by first
resizing the muzzle of the shell and forcing the bullet, base
first, back into the shell to the required depth. This method of
seating bullets requires considerable care to avoid injury to the
base of the bullet or scraping the sides of the bullet as it is
pushed down into place. It should be remembered that crimping a
shell does not add to the accuracy of the cartridge and the less
crimping that is done on bottle necked shells, the better results
will be obtained.
Bullets for reduced loads in high-power rifles
are made of one part tin to ten parts lead. Pure lead bullets
cannot be used in rifles with quick twists on account of the metal
being too soft to prevent the bullet from stripping as it goes
through the barrel. While tin gives the bullet toughness and
hardness, it has the disadvantage of having a lower melting point
than has lead. Lead melts at 626°F, while tin melts at 451 °F, and
volume for volume, lead is almost twice as heavy as tin. However,
tin is the most satisfactory metal that can be used with lead to
make a bullet for the lighter smokeless powder loads. Antimony is
often added to bullet metal to give it hardness and prevent
stripping, about 3 to 5 per cent, being sufficient. Antimony melts
at a temperature slightly higher than that of lead and is only a
trifle heavier than tin. It makes the bullet hard and somewhat
brittle, and unless absolutely necessary to prevent stripping, it
is probably best not to use this metal. Antimony will not mix well
with lead without the addition of a small amount of tin and it
possesses the peculiarity of expanding on solidification.
Sometimes it is difficult to secure block tin, and solder,
containing half tin and half lead, can be used.
MOULDING bullets requires a little practice.
The metal should be heated in an iron kettle over a gas or
kerosene flame so that the heat can be regulated easily and kept
uniform, a requirement for the moulding of good bullets. A dipper
made for the purpose, having a nozzle which fits the pouring hole
of the cut - off on the mould, should be used if the best results
are expected. Before beginning to use the molten metal, drop in a
small piece of tallow or a few drops of oil and stir to flux the
metal and make it flow easier. Keep the metal at as low a
temperature as will enable it to flow freely and make good smooth
bullets.
If it is heated to a temperature too high the
metal deteriorates rapidly and the bullets will be porous. The
mould must be kept hot, and if a pair of cotton gloves are worn on
the hands the work of moulding bullets will be made more pleasant.
As the bullets come from the mould they should be allowed to fall
gently on a piece of clean cotton cloth where they can remain
until cool. As a rule new bullet moulds do not cast good smooth
bullets until they have been used a short time and the interior
surfaces of the mould have become oxidized. The mould must be kept
clean and well oiled or it will soon become useless.
A bullet of 125 to 150 grains weight makes a
well balanced bullet for reduced loads in high-power rifles of the
30 calibers and about 80 or 90 grains weight is most satisfactory
for high-power rifles of the 25 calibers. If lighter bullets are
used the powder charge must be reduced to prevent stripping and a
longer and heavier bullet is liable to tip in its flight after
leaving the muzzle of the rifle and destroy its accuracy and
efficiency.
A high-power rifle sighted for high velocity
ammunition will not shoot short range loads correctly. Such a
rifle will shoot to the left and a little low when used with the
short range loads, therefore an adjustment of the sights must be
made if accurate shooting is to be done. Should the rifle be
equipped with a peep sight, similar to Lyman's No. 103, which has
a very fine adjustment for both windage and elevation, the problem
of keeping the rifle sighted for both short range and high
velocity loads becomes an easy matter. By marking the stem above
the adjusting sleeve and marking the windage adjustment for point
blank range with high velocity ammunition at a range of about a
hundred yards, and making similar marks for the point blank range
with short range loads at about fifty or seventy-five yards, the
rifle is very quickly adjusted for either of the two loads.
IF trouble is experienced in having shells
stick in the chamber of the rifle, the difficulty can be remedied
by resizing the entire shell in a resizing tool made especially
for the purpose. To resize a shell, the exterior surface should be
wiped with an oily rag and the shell driven into the resizing die
with a wooden mallet. If the resizing tool rests upon a solid
block of wood it will expedite the driving of the shell into the
die. Driving the shell in and out of the die will reduce it to a
size that will enable it to enter the chamber of any arm freely.
Loaded cartridges must not be resized in this manner and no
success can be obtained in resizing shells that are bent, annealed
or corroded.
Alloy bullets should never be fired in a barrel
following the shooting of high velocity ammunition, without first
cleaning out the barrel, as the residue of the heavy load may
cause leading of the barrel. However, it is not necessary to clean
out the barrel after using short range loads before shooting high
velocity cartridges. All alloy bullets should have the grooves
well filled with a good lubricant. A very good lubricant for
bullets can be made from beeswax softened with cylinder oil, or
pure vaseline hardened with paraffin. In either case the materials
that go into the making of the lubricant must be perfectly pure
and free from acids of any nature. A contrivance for packing the
lubricant into the grooves of the bullets should be purchased or
made by the shooter himself. Such an article can be made by
cutting off the base of a cartridge shell having the same diameter
at the mouth as the bullet used, and after filling the grooves
with the lubricant, they should be forced, point foremost, up
through the shell. Be sure there is no lubricant left on the base
of the bullet to come in contact with the powder and deteriorate
the powder charge in the loaded shell.
The writer has had considerable experience in
using short range loads in high-power rifles for shooting small
game and has found them more satisfactory than a 32-20 or 25-20
rifle which are often used for such shooting. My favorite rifle is
a 303 and I have never had any trouble with the short range loads
working through the magazine or sticking in the chamber of the
rifle barrel, and I never go to the trouble of resizing the empty
shells. With a supply of short range loads and a few high velocity
loads, one is well prepared for any game that may be seen during a
day's hunt.
A FEW words about the choice of a bullet would not be out of place in this article. Choose a bullet that is well balanced and combines appearance with other desirable qualities. There are a lot of queer-looking freaks among the various styles of bullets as well as everything else on the market. A sportsman should not stop with the choice of a well balanced and artistically appearing rifle, but he should demand the same qualities in the shells and bullets which he uses. It serves not only to develop a sense of the beautiful, but it gives one more pride in the things which he possesses.
