Trooper Wrote:The three things that a GPC would need is a BC over .500, muzzle speed of 2500 fps and potential to be used in the M16/M4 platform. But my question would be whether there is ANY advantage of going to a larger caliber (ie 7mm), of using a longer case than what we have in the 6.5 Grendel. How close is the Grendel in potential to becoming the GPC?Bill Alexander estimates the Wolf 100gr FMJBT to have a 0.390 BC, quite a bit lower than the 0.500 you cite as necessary.
A larger caliber (6.86mm or 7mm) may be required for a GPC to have adequate terminal effects, particularly with lead free bullets.
