6.5x47mm Lapua (or 6.5x47mm) is a rifle cartridge that was developed specifically for 300m competition by ammunition maker Nammo Lapua and the Swiss rifle manufacturer Grünig & Elmiger AG in 2005.[1]

FeaturesEdit

The cartridge has many special features including:[2]

  • The cartridge chamber dimensions are optimized for target bullets.
  • High pressure level (435 MPa / 63090 psi) and optimized powder capacity enables high velocity and flat trajectory.
  • Reduced barrel wear compared to 6mm Norma BR.
  • The 6.5x47mm Lapua has a base diameter and overall length similar to the 7.62x51 mm, allowing it to accept the same bolt heads and fit into similar actions and magazines.

PerformanceEdit

The 6.5x47mm was designed from the beginning by Lapua to optimize accuracy, barrel life, and case capacity in a 6.5mm cartridge for target shooting. It is proving superior in these attributes when compared to other 6.5mm cartridges for competition shooting.
