L’innovazione
brevettata MRR Bullets.

The Problem

Monolithic copper bullets are harder than lead.

During compression in the rifling, this hardness generates greater friction, deposits copper residue in the bore channel, and introduces micro-variations in the harmonic vibrations of the barrel, variations that translate into dispersion on the target.

The Solution

The solution developed by MRR Bullets affects the geometry of the empty spaces between the bullet’s forcing crowns. Instead of maintaining them cylindrical, as in traditional production, the shape progressively varies from cylindrical to truncated cone-shaped.

This seemingly minimal geometric change completely alters the material’s behavior under pressure: the copper migrates laterally in a controlled manner, reducing friction, limiting deposits, and stabilizing the harmonic vibrations of the barrel.

.01
Forcing Crown

The design of MRR Bullets facilitates the movement of material during the compression of the bullet in the rifling, reducing the deposits of residue inside the barrel and improving the consistency of the harmonic vibrations of the barrel, which in turn affects the accuracy of the weapon.

.02
Performance under Pressure

The design of MRR Bullets facilitates material displacement during projectile compression in the rifling, reducing residue buildup inside the barrel and improving the consistency of harmonic barrel vibrations, which in turn affects the weapon’s accuracy.

.03
Multi-Radial Rifling

The design of MRR Bullets facilitates material displacement during the compression of the bullet in the rifling, reducing the buildup of residue inside the barrel and improving the consistency of harmonic barrel vibrations, which in turn affects the accuracy of the weapon.
