Trooper Wrote:As a general purpose cartridge (GPC), the big advantage of the Grendal is that it works in the AR15/M4 platform yet gives .308 performance. If we could use a bigger platform (ie AR10), what would be the ideal cartridge? My basic metrics are fps (2500 seems to be the sweet spot), Ballistic Configuration (the Grendal is seem be at .540, not sure what a 7mm would have to be to compete) and performance at 500 to 1000 meters.What you are describing is essentially the hypothetical "6.5 GPC" that Guardsman26 and Tony Williams seek to have developed.
