I think people are missing a trick here. The 6mm Arc with a 26 inch barrel in a 1 in 7 twist can push a 109 Berger Hybrid at 2850 fps and has a barrel life well over 4000 rounds. Most 6mm cartridges I'm aware of are either barrel burners or only good for shorter distances and lighter bullets. Surely there's a place in the UK market for a cartridge like this?
