I am trying to decide on a barrel for the 6.5 grendel.  Shorter and lighter is always better for handling, but I want this grendel to perform at long range.  What velocities have you guys been seeing with the 123's in different barrel lengths.  I'm kinda headed toward a 18-20" barrel but will go longer if the velocity is boosted enough to help at long range.

20-25fps/inch holds true for almost every caliber. A 20" will be 100fps faster than a 16"

I have been trying to get my .264LBC built, but the parts keep selling (joys of owning the shop). But, I'm going to use a Blackhole Weaponry 22" barrel. In my discussions with BHW, expect to see 50fps per inch. Now this is only for their polygonal rifling. A BHW 22" will shoot velocities like a 24" 5R (and so forth).
