6.5 x 47 Lapua

In 2005 the Europeans invented a 6.5 Cartridge specifically for 600 – 1000 meter matches.  It was its own case, developed to be the same head size as a 308 cartridge but similar in proportions to a 6mm PPC – having an excellent case volume to projectile diameter.  As a result, the 6.5 x 47L has more barrel life than a 6mm BR.

The 6.5 x 47 L case was developed to have a small rifle primer and a strong case web (the base of the case) meaning this cartridge was proofed at 78,872 PSI, but can comfortably handle 63,000 PSI.  Similar cartridges struggle at 58,000 PSI – evidence of this was the first few batches of Hornady 6.5 Creedmoor ammo that caused pierced primers.  So, while the 6.5×47 Lapua may be one of the smaller 6.5 cases, it performs out of its league.

6.5 projectiles are very long – hence why the normal barrel twist for .264 barrels is 1/8” or 1/200mm.  This gives them excellent long range performance – better than many 30 calibre rounds over 1000 meters, but with only mild recoil.  These long projectiles, with their high sectional density, are also very good on medium sized game due to their deep penetration (with projectiles designed for game hunting, of course).  Hornady also produce a 95gr v-max projectile specifically for varmint hunting, giving this calibre even more versatility.

Production rifles in this calibre are thin on the ground, but if you’re after one nice rifle for a variety of different types of shooting, a custom rifle in 6.5 x 47L is definitely worth considering.
