1. Bullet Manufacturing


  • Consistent geometry (CNC manufactured).
  • Mid SAAMI tolerance on diameter (± 3,5 Micron (µm) maximum on manufacturing).

2. Technical Features of Bullet


2.1 Material

  • Pure copper (>99,5% copper).
  • Environmentally friendly (lead free).
  • Aligned with international trends (embargo on leaded ammunition).
  • Specific gravity of pure copper is 10 – 15% less than equivalent lead core bullets. The monolithic bullet is lighter than the equivalent length lead core bullet, therefore increased velocity is achievable.
  • By selecting the appropriate monolithic bullet for a given twist rate, a flatter trajectory may be achievable compared to the lead core alternative. Follow manufacturer’s recommendation on selecting an appropriate bullet weight for the rifle’s twist rate.

2.2 Rebated Boat Tail

  • Deflected gas flow away from the bullet during bullet exit at crown, ensuring less turbulent gas conditions in front of the bullet.
  • Up to 15% increase in precision and accuracy compared to conventional boat tail design.
  • Flat base bullet precision and accuracy with boat tail BC benefits.
  • Boat tail angle conforms to the popular industrial standard for optimised BC.

2.3 Ogive

  • Tangent Ogive design which is less “jump” sensitive.
  • Ogive is not off a “bore rider” design, i.e. the ogive engages with the lands.
  • Bullet is “tunable” for precision (i.e. jump adjustable).
  • Bullet position in case can be measured with ogive comparator tools.
  • Both a “target” and “hunting” ogive designs available. Same impact point.

2.4 Bearing Surface

  • Designed within SAAMI tolerances.
  • Improved low friction drive band design which results in:
    – Minimum copper fouling
    – Low pressure characteristics

3. Hexagonal Boron Nitrate (HBN)


Hexagonal Boron Nitrate is widely used in industrial applications due to its excellent dry lubricating properties and ultra-high-temperature abilities. Hexagonal Boron Nitrate has the best combination of high temperature resistance and lubricating properties, out of all solid lubricants available today.

3.1 Excellent Lubrication

  • HBN application results in less fouling and less pressure compared to untreated monolithic bullets.
  • Reduced extreme velocity spread and therefore improved precision and accuracy.
  • Improved accuracy between cold bore and follow-up shots. Further reduces elevation dispersion.
