[edit] Features
Features touted by Lapua[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
- Low wind drift makes shots especially accurate
- Reduced barrel wear compared to 6 mm BR Norma
- The 6.5x47 Lapua has a base diameter and overall length similar to the .308 Win., allowing it to accept the same bolt heads and fit into similar actions and magazines
[edit] Performance
The 6.5x47 is essentially a european-made equivalent of David Tubb's 6.5 XC.
