Norma Brass is the gold-standard of cartridge cases.
This 6.5mm variant is quite a new development, created in 2007 by a cooperation between Hornady and Creedmoor Sports and was designed as a long range target shooting cartridge. The 6.5mm bullet has long been known to be an excellent long range bullet, as the projectiles have good sectional densities and ballistic coefficients and the 6,5 Creedmoor has become very popular for long range hunting. The case is on the shorter side so it can be chambered in a short action rifle.
