One thing I have noticed is the numerous references to 6.8 loads with the 85gr bullets at velocities at or over 2800 fps, and then using that as an example of the superiority of the 6.8 SPC to the Grendel, when I don't even recall anyone trying any 85gr projectiles in the Grendel yet, since 100gr is considered on the light end of the scale.
One advantage that some PDW builders using the SPC have related to me at SHOT is the unusually high velocities out of that cartridge from 7"-10" barrels, which is nice for a select few organizations out there in the diplomatic/VIP security arena, aside from the logistics and magazine capacity issues. I don't think anyone has even tried that with the Grendel yet, since most Grendel advocates are really pushing the downrange capabilities of the cartridge with longer barrels. I will say that before I loaded up some 100gr Nosler BT's, I had pretty much written the Grendel off as an assault rifle cartridge. After shooting those out of my A2 comp'd 16", a new bug started scratching me, but I'm still a well-convinced 5.56 Nazi when speaking strictly about an assault rifle or carbine for riflemen and special operations soldiers acting in an assaulter of dismounted shooter role, without any specialized tasks based on precision marksmanship.
We haven't even really looked at the potential of the Grendel in the CQB to 300m range as far as dedicated lightweight projectile loads go. I'll bet that the 100gr NBT out of the Grendel also makes a great 400m pill too. I really need an enhanced bolt from AR Performance if I'm to push the loads to where I think they can go for light projectile/high velocity in the Grendel. Harrison makes those bolts for the 6.8 and 7.62x39 already.
