Optimum 6.5 Grendel bullet weights

[JASmith]

BALL
[img]...In 5.56 NATO, a 62gr projectile is standard. Some people consider 110 grains to be "just right" for a 6.5 ball load. What weight do you think is best for 6.5 Grendel, and why?

Look at 95 -100 gr bullets with AMAX shape -- they seem to come closest to the M855 trajectory out to 500 meters.

SMK
[img...In the 5.56 Mk262 load, 77gr is the projectile weight. The only 6.5 SMK factory load currently on the market has a 123gr bullet. What weight SMK do you think would be best for 6.5 Grendel, and why?

Can go heavier terminal performance and drift resistance more important for what appears to be a sniper mission -- The 140 gr MK likely too heavy. Consider the 130 gr Berger VLD (high ballistic coefficient and similar construction to MK, so might be allowable under JAG guidelines)

TSX
[img]...Another special purpose bullet, mainly used in the 10.5" barrel, Mk18 CQB carbine. In the 5.56 "brown tip" load, 70gr is the bullet weight. The only 6.5 TSX factory load currently on the market has a 120gr projectile. What weight TSX do you think would be best for 6.5 Grendel, and why?

Any weight of 100 gr or better will better the SD of the 70 gr .24" bullet. The 120 gr TSX would do just fine in this role - provided JAG allowable.
