Quote:I am in strong favor of a High Performance Intermediate Cartridge like the Grendel for a new Multi-Role belt-fed LMG, which could replace the 7.62 GPMG in the dismounted role. That will take at least a 130gr bullet at anywhere from 2600-2750fps, although 2600fps is plenty. A mass-produced 130gr FMJBT with lead core would have no trouble facilitating a .500" G1 BC.Trouble is, it appears very unlikely that anybody will want to use a lead-core bullet.
The trend in Western countries is to "green" bullets, and Eastern Europe seems likely to use conventional steel-core projectiles. I'm skeptical that weights of such bullets could, in practical designs, exceed 110-120gr. So, if the MRLMG requires 130gr or heavier projectiles, 6.5 Grendel does not look like a viable choice.
