It was designed by Lapua with a great deal of help from Swiss rifle manufacturer, Grünig & Elmiger.

(Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the 6.5×47mm Lapua can handle up to 435.00 MPa (63,091 psi) Pmax piezo pressure.

regulated countries are currently (2018) proof tested at 543.80 MPa (78,872 psi) PE piezo pressure.

[8] It was designed from the beginning by Lapua to optimize accuracy, barrel life, and case capacity in a 6.5 mm cartridge for target and tactical shooting.

[1] 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.

[13] American Kevin Nevius set a new NRA national record for high power rifle with a perfect score of 200-20X at 600 yd (549 m) – 20 shots (Prone-Any Sight).

[14] The 6.5×47mm Lapua has set a new record in October 2017 for bench rest in the UK with a five shot group measuring 1.058" and on a blustery day at 600 yd (549 m).

This wildcat cartridge is often called a 6-6.5×47[16] to avoid confusing it with the 6×47 Swiss Match,[17] a similar case but with a large rifle primer.
