16" AR 6.5 grendel guys velocity questions

123 ELD at 2400. 28.2gr of A2460, CCI 450 primers, Starline brasss. I’d try for more speed, but that load is sub 1/2 MOA out of a 16” Faxon gunner, so that’s the load. It’s fast enough to put whitetail in the freezer.

120 Nosler BT over 8208 is roughly 2440.
123 ELDm over Benchmark is around 2340 if my notes are correct.

16" mid length gasser.

I really like 8208 but i am reserving what I have left for the 223.
