It is a seriously cool cartridge

It is shorter than the 260 which can suffer if you want to use high BC bullets because they rob the case of its capacity in some 308 length magazines. Its about 2/3 the length of a .308 or just about half way between the 6mmBR and the .308. I think it was designed for 300m CISM competition and has the advantage over the BR because the extra case length enables easier feeding from a magazine. It is apparently ideal for 600yard shooting according to David Tubb and the 6mm necked down case 6-6.5x47 is becoming very popular for 1000yard F class. I'm having one built as a stalking rifle because I think it is the perfect deer cartridge for the UK, including open hill stags in Scotland. The plan is to use 130 grain Scirroccos. The prospect of Reloder 17 powder is also pretty exciting. Lapua reckon it is the most efficient case possible on the 308 case head. Lapua brass, high BC 6.5mm bullets, benchrest proven powders, small rifle primer, how can you go wrong? I can't wait!!
