Ballistic Meplat Uniformer (BMU)
The next step in rifle
ammunition performance

"This tool provides the serious shooter a new
opportunity to improve his ammunition. It does for bullets what neck turning
does for the case -- it perfects them."
The Ballistic Meplat Uniformer (BMU) allows the shooter to
equalize the ballistic coefficient (BC) of like kind and weight bullets. In
other words, use of this tool will uniform the BCs of your favorite bullet or
even factory ammunition. It does this by uniforming the bullet's meplat (the
diameter of the tip at the nose of the bullet). In addition, the BMU also
uniforms the length of the bullet's frontal section (the distance from the full
caliber diameter nearest the front of the bullet to the tip of the bullet).
Furthermore, our tests have shown that uniforming the meplats on a box of 100
match bullets and reweighing them virtually eliminated the usual weight variance
encountered in non-uniformed bullets.

Uniforming the meplat reduces the ballistic coefficient of the bullet by
approximately 2%. However, it results in more consistent shot placements --
smaller groups. This improvement is magnified the farther the shooting distance.
Your groups will be smaller and your downrange shot-to-shot chronograph readings
will be closer together; therefore, your rifle and
ammunition combination will show an increase in repeatable shot-to-shot
performance.
Most long range shooting involves using relatively long
powder column cases, slower burning rate powders, and long, heavy secant
(sharper) ogive bullets. This combination means, one, that reducing velocity
spreads is of great significance given the volume and rate of the propellant and
also that the sharper and longer the bullet is the less stable or sensitive it
is inherently, unlike 100 and 200 yard benchrest shooters who typically use
short powder columns, faster burning rate powders, and lighter weight tangent
(more rounded) ogive bullets (by the way, there are bench rest shooters using the
BMU). Any inconsistencies in one's ammunition are magnified the farther the
bullets travel. Experienced long range shooters know that points lost to
elevation (shots hitting higher or lower on the target face) are the most common
symptom of ammunition inconsistencies.
When accurate ammunition loading techniques are utilized,
the BMU has demonstrated that downrange velocity readings (extreme spreads) can
be cut in half compared to non-uniformed bullets and even show occasional
identical velocity readings from one shot to the next -- this almost never
happens with bullets that have not been uniformed. The on-target results are
overall smaller shot groups.
This product is currently being used with great success by
1000-yard bench rest shooters as well as across-the-course High Power Rifle and
Long Range target shooters. All have commented that the BMU makes their groups
rounder by minimizing "fliers" (less vertical dispersion). Across-the-course and
Long Range target shooters tend to notice that BMU use makes their rifle shoot
flatter groups (minimizes elevation shots); since their course of fire is
typically shot over a longer time period they are more susceptible to wind and
mirage changes.
If you want your ammunition to exhibit a noticeable
accuracy improvement, this is a step the serious shooter simply cannot afford to
skip. Chances are that your competition will be using it!
