Hate to tell you guys this but he talked about using 100 round drums of 5.56 loaded completely with tracer and training the soldier to use full auto and walk the shots into the enemy. No sights, just tracer. I am sure he was not pushing a 100 round drum and straight tracer. Rather emphasizing a point about getting effective fire on to an enemy quickly and that doesn't need a huge amount of training to accomplish.The 6.5x39 AK?
He did not seem to be a proponent of going back up in cartridge caliber.
If given a choice of some sort of AK design firing a 6.5 X 39 cartridge and a AR-15 with a C Mag of tracer, guess which one I would choose?

This video from October 2016 shows a Serbian demonstration that was done using PPU commercial 6.5 Grendel ammo.
PPU 6.5 Grendel ammo visible @ 4:11-4:18 and 6:03-6:26

Hardened Steel core (Ball?) -- 6.0g (~93gr) ---- 880mps (~2885 fps)
Tungsten Carbide core AP ---- 7.3g (~113gr) --- 800mps (~2625 fps)
