Ballpark velocity of BH 75 BTHP out of 16" AR?

[deersniper]

Does anyone know what the velocity of Black Hills .223 75 grain BTHP should be out of a 16" AR (LaRue stealth)?

I have a chrono and know how to fiqure out velocity by shooting at 100 and 600 yards, but I don't have time for that and am trying to make a drop chart that is somewhat accurate.

Thanks for any and all help.

Thanks for the info, I already made a chart for 2600, I will make a new one for 2560 and use that.

Thanks.
