For those of you shooting 16" Grendel ARs, what velocities are you getting with your 120s and 130s? (or any weight for that matter)

Depends on many things. But roughly, you should be able to get the 120s at about 2420ish. If you use cfe223 or lever, you'll probably get closer to 2500.
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.

Ok, bc vs velocity question for your ballistic solvers. In Strelok pro, I threw a load in there that was typical of what I used to shoot. A berger 120 (g7 [email protected]) at about 2330fps in the warmer temps (around 70) With that, at a thousand yds, I get 15.3" of spin drift deflection with a 0mph wind, 153.3" of deflection w/ a 10mph 90 degree wind, absolute drop of 504", & 1198fps final velocity.
When I bump up the BC to .287 with the bergers 130s at approx. 2250mv, it spits out 13.9" of spin drift deflection w/ a 0mph wind, 88.1" of deflection w/ a 10mph 90 degree wind, absolute drop of 499", with a final velocity of 1296.
It appears to me that pushing a high bc bullet with a slighly slower MV yields way better results. Though, it kind of seems to good to be true.
Do you solvers tell you the same thing?

The 130s bc is 20% higher. It’s going to do better at long range. The further you shoot, the more important its ability to move through the air without drag.
Higher velocity on less aerodynamic bullets builds drag and quickly its full-steam-ahead approach boils out. A more aerodynamic bullet maintains its composure better, longer, and thus further.

8208 and 123 eld is a great combo. I used to get 2450 in my 14.5 " barrel.
no, it was a mid length not carbine gas system. Ive run around 28.5 gr through may rifles and have found if my rifle likes factory hornady match this combo will work as well
