Ballistic Meplat Uniformer (BMU)

 The next step in rifle ammunition performance

Ballistic Meplat Uniformer (BMU)

 

"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.

Ballistic Meplat Uniformer (BMU)

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!
