re: 300 BLK Bolt Action

The grendel is a good round but needs a very long barrel to compete with a 16" 308.

The 6.5 Grendel outperforms the 308 in flight out of the same length barrel. The 308 will obviously carry more impact energy because it shoots a heavier bullet with more case capacity, but no length Grendel barrel will close that gap, enter the 6.5CM.
