In an article by the Precision Rifle Blog a survey of the top 100 shooters in the precision rifle series (PRS) showed that the 6.5 Creedmoor was on average  faster than the 6.5×47mm Lapua.
The 6.5×47mm Lapua offers slightly lower muzzle velocities than 6.5 mm/.260 cartridges such as the 6.5 Creedmoor and .260 Remington due to its smaller case volume.
