1. Military rounds are not just about what they do to humans. The ability to perforate cover is absolutely critical.
I say again, the ONLY "cover" that PDW rounds can perforate reliably is CRISAT. And none of our current or foreseeable enemies is stupid enough to wear body armor to the battlefield. PDW rounds against "real" cover are worse than useless. Light, fast bullets just don't penetrate very well.

One more point on PDWs and "itty-bitty bullets" IOT save weight. I guaran-freaking-tee you, that a lightweight "bullet-hose" PDW will go through ammo fast enough, that will more than neutralize the alleged "weight-savings" versus a "real" rifle.
