This BERSIN Ammunition Measuring and Adjustment
Device is a revolutionary invention in precision shooting. The device
diagnoses and eliminates errors in the longitudinal axis in rifle ammunition
(concentricity flaws).
Unlike other tools, the device allows each cartridge to be solidly fixed
within a replica of a rifle cartridge chamber for measuring purposes. Its
accuracy of measurement - particularly of repeat functions - is unique.
Furthermore, this device is the only existing tool available today which
allows you an exact adjustment of cartridges containing concentricity flaws
with respect to uneven alignments of the projectile within the cartridge
case. In addition, the device discovers uneven cartridge case surfaces and
irregularities in the seating depth (total length) of your ammunition.
Many different types and calibers of ammunition contain concentricity flaws.
Industrially manufactured ammunition generally contains errors of 4/1,000”
to 20/1,000” (measured in the region of the projectile’s tip). Flaws of up
to 40/1,000” are not uncommon. A shot at a distance of 300 yards with such a
shell will forcibly miss its target by approximately a foot due to the
provoked rotational imbalances.
Even carefully reloaded cartridges may contain errors of 4/1,000” or more,
caused by minor mistakes in the reloading process, such as a bad angle of
insertion of the projectile in the case mouth. The device generally reduces
these errors to 1/1,000” or less.
Through the alignment of the projectile’s axis with the axis of the
cartridge case, while firing the cartridge, the projectile is pressed in a
precise manner into the barrel throat. This avoids rotational imbalances of
the projectile in the barrel and in the trajectory.
Rigorous testing in different atmospherically neutralized facilities has
confirmed the efficiency of the BERSIN device and has demonstrated, that by
means of a simple process of manual measuring and adjustments of the new or
reloaded ammunition, the precision of your rifle shot can be improved by up
to 50%.
Whether you are a marksman using industrially manufactured ammunition or you
are a reloader, this device is designed for you. It will ascertain and
minimize flaws which occur in serially produced ammunition, as well as
alleviate many problems of eccentricity in reloaded cartridges.
The device allows for the quick measurement of the accuracy of the cartridge,
and if needed, for an instant adjustment of the projectile with the axis of
the cartridge case, all of this being accomplishable within seconds. It can
be used for all types of shooting - particularly sport and precision
shooting, bench rest shooting, or for hunting and security purposes.
More precise ammunition means an improvement in your shooting accuracy and a
decisive reduction of your target diameter. |
