The 8.6 BLK round was imagined and developed by Q.
When imagining 8.6 BLK, a good starting point is to think of 8.6 BLK as 300 BLK's "Big Brother." However, it's much more than just an upgrade on 300 BLK.
8.6 BLK is re-imagining "energy on target" by employing a fast 1:3 twist rate (compare to common 1:7 and 1:8 twist for calibers like 5.56 NATO or 300 BLK).
