Grendel as a Universal Infantry Cartridge

[cory]

...Having managed men, weapons, and equipment in PACOM, SOUTHCOM, and CENTCOM on real-world deployments in airborne and light infantry units, I know what a bad thing it would be to have my Joe tentpeg riflemen slinging 120-130gr projectiles in close quarters. It would be beautiful in true Lightweight Squad-support belt-fed weapons, and precision Semi-Auto Systems, which have not received the same attention that carbines have...

That would be no worse than Joe slinging 62gr projectiles in CQB situation, with poor tactics and inadequate battlefield awareness.

The more I think about the more I'm a proponent of Joe slinging a 200-230gr projectile in CQB environments. A 10mm or 45acp. Adequate energy at the muzzle and it sheds that energy relatively quickly. This is assuming we use "Open Tip Projectiles".
