PROVISIONAL SPECIFICATION
Improvements in Projectiles for Target Practice with Fire Arms.
1, ARMAND MIEG, of No. 64 Weststrasse, Leipzig Saxony, do hereby declare
the nature of this invention to be as follows:-
My invention relates to a manufacture of specifically light projectiles for target
practice, composed of either a single light material or of a combination of light
materials, and which is introduced into moulds of the requisite form, either coll
or hot, and either with or without admixture of binding materials.
The form of such projectiles is generally spherical, as elongated projectiles which
are prepared in a similar manner to spherical ones do not afford sufficient precision
in firing.
The material or mixture of materials, and, when used, the binding material,
should be so chosen that the projectile possesses the requisite cohesion, and in
particular such that it will not have its form altered or be broken up by the shock
of the explosion on firing or in passing through the barrel of the gun.
The projectiles are for this purpose subjected to more or less pressure in the
moulds.
The light material employed may be, for example, clay, paper material, sawdust,
cellulose, wood fibre &c. As binding material may be used gypsum, glue, albumen,
caoutchouc, shellac, collodion &c.
In particular a mixture of sawdust with sorel-cement (burnt magnesia and
magnesium chloride) gives a good result.
If somewhat heavier projectiles are required for more distant targets, there may
be mixed with the light material or mixture, metal powder such as brass or lead
powder &c. In any case the material or mixture chosen must be such as not to
injure the rifling of the barrel.
Projectiles of the above described kind can ordinarily be used for target practice
up to a distance of about 25 yards, but they can be made available for 50 yards and
more, according to the weight given them. They will pass through two sheets of
paste board, each of from 15 m.m. to 2 m.m. thick, and will then carry about
100 yards beyond. When using an admixture of metal powder the weight of the
projectile can be adjusted within certain limits for a great variety of ranges.

Improvements in Projectiles for Target Practice with Fire Arms.
I, ARMAND MIEG, of No. 64 Weststrasse, Leipzig, Saxony, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :--
My invention relates to a manufacture of specifically light projectiles for target
practice, composed of either a single light material or of a combination of light
materials, and which is introduced into moulds of the requisite form, either cold or
hot, and either with or without admixture of binding materials. The form of surh
projectiles is generally spherical, as elongated projectiles which are prepared in a
similar manner to spherical ones do not afford sufficient precision in firing.
The material or mixture of materials, and, when used, the binding material,
should be so chosen that the projectile possesses the requisite cohesion, and in

of the explosion on firing or in passing through the barrel of the gun.
The
projectiles are for this purpose subjected to more or less pressure in the moulds.
The light material employed may be, for example, clay, paper material, sawdust,
cellulose, wood fibre &c. As binding material may be used gypsum, glue, albumen,
caoutchouc, shellac, collodion &c.

be mixed with the light material or mixture, metal powder such as brass or lead

injure the rifling of the barrel.
Projectiles of the above described kind can ordinarily be used for target practice
up to a distance of about 25 yards, but they can be made available for 50 yards
and more, according to the weight given them. They will pass through two sheets
of paste board each of from 1-5 m.m. to 2 m.m. thick, and will then travel about
100 yards beyond.
When using an admixture of metal powder, the weight of the projectile can be
adjusted within certain limits for a great variety of ranges.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Projectiles for target practice having a limited penetration and range, formed
of a specifically light material or combination of light materials, such as clay,
paper pulp, wood fibre and the like, with or without adınixture of cementitious
material, and with or without admixture of metallic powder, substantially as
described.
2. The manufacture of projectiles for target practice composed of a mixture
of sawdust and sorel cement, with or without addition of metallic powder, sub-
stantially as described.
