6.5x47mm Lapua

6.5x47mm Lapua (or 6.5x47mm) is a rifle cartridge that was developed specifically for long-range benchrest shooting by ammunition maker Nammo Lapua and rifle manufacturer Swiss Grünig & Elmiger AG in 2005.

Features
The cartridge has many special features including: :
 * The cartridge chamber dimensions are optimized for target bullets.
 * High pressure level (4350 bar / 63090 psi) and optimized powder capacity enables high velocity and flat trajectory.
 * Reduced barrel wear compared to 6 mm BR Norma.
 * The 6.5x47mm Lapua has a base diameter and overall length similar to the .308 Winchester, allowing it to accept the same bolt heads and fit into similar actions and magazines.

Performance
The 6.5x47mm is essentially a European-made equivalent of David Tubb's 6.5 mm XC.
