I went onto JBM just to play with it and at Sea level @ 60˚, you will need to be well above 2800 FPS using a Sierra 168 OTM. I've read the Hornady 168 A MAX can work a bit better, but if you try to get a 308 Winchester with a 168 bullet well over 2800 FPS, you're straining your equipment.
I don't recommend using a bullet that requires you to use max load to get where you need, just in case there isn't a accuracy node that high up. I think the 175's are the popular choice.

At 1k with 168's your conditions have a huge effect
If your tied to the 168 weight bullets, if I recall it was primarily the 168 Sierra Match King that suffered this transonic problem. If I recall it had to due with the angle of the boat tail. The a-max I have had first hand out shoot the SMK
175's work better for me, and if your after higher FPS check out the 155 class.
The problem with 175's is they can be hit or miss with 1/12 twist
I use the 155gr A-Max and if you run it at 2900fps, the velocity at 1K is still 1294fps. If you look at a comparison of wind drift and TOF (time of flight), you may find out that the 155 is a much better way to go.
