[edit] Features
The cartridge has many special features including: [2]:
- 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.
[edit] Performance
The 6.5x47mm is essentially a European-made equivalent of David Tubb's 6.5 mm XC.
