New Cartridge Developments and Implications for Dismounted Infantry Soldiers

[stanc]

I'm thinking a more ideal cartridge for what we're looking at would have a narrower base diameter like the Grendel at .444", with more cartridge length for powder capacity, and would give a better over-bore relationship for barrel life if used with a .264" bore. Basically, a longer base-to-shoulder Grendel would seem ideal at this point, given that we aren't limited by mag-length.
