Hello, new to the forum and new to the Grendel, was looking for ballistics on Hornady ammo 123grn Amax past 500yrds. Eager to learn any help would be greatly appreciated. Thank you

Not meaning to be an arse, but that is like asking how fast 98 octane gas will make my car go.
Way too many factors to take into account for specifics, the big one being Muzzle Velocity.
If you post info on your rifle, then we can guesstimate something for you. You can also check out several online ballistic calculators and enter in the variables that you know.
Try this one from Vortex. It will give you an idea of what you may expect.

Go here, if you have vortex glass the second option is way cool.

A Friend and I have four 6.5 Grendel AR-15's between us and he also owns a Magnetospeed chronograph. These velocities and Ballistic calculator should give you an idea of the 6.5 Grendel performance. There is a graph showing approximate velocity loss or gain for different barrel lengths if you go shorter than 16" or longer than 24".
Here is a list of the tested ammo by average velocity for each barrel length.

There is also a google custom search which is very handing in looking up data or threads which have been previously posted on the 6.5 Grendel forum.
