Los 7mm se han descartado."On 17th June 2003 I received an email from a Cris Murry: "This is a reply to the guess work all the supposed smart people are doing on the 6.8x43mm. It would appear that our operational security is working real well. But here are a few bits for you guys to chew on. Its not made from a .25 Rem. case, or reforming .223 brass, how do I know, I designed it. It has nearly the same flight path as the 7.62x51mm M80 ball round out to 650 meters. Delivers approx 4 times the energy on target at 300 meters compared to a SS109 round. The gel block tests are awesome. It drops a 150-300 lbs feral hogs like an axe, also works great on whitetails. My first choice was 7mm projectiles, but the users wanted something with a flatter trajectory, closer to the 5.56. Tested all calibers 6mm, 6.5mm, .25, 6.8 (.270 for Americans, oh actually the Chinese came up with the 6.8x63mm in the 1930s), didn't do much testing in .30, because it would only be an American M43 cartridge. This was not a private endeavourer nor a fully sanctioned government project, just users and a gun builder making a better product for our guys on the ground, in harms way." " "Many thanks to Stan Crist for forwarding the following Press Release from Remington. "The 6.8mm Remington SPC is an intermediate length rifle cartridge based on the 30 Remington case.
