That's why I indicated this applied to the load referenced. Of course you can exceed 2800 fps with a 155 grain bullet or less. If you want to argue that the difference is greater, then provide some statistics for a given load rather than just making a random statement.

It doesn't make sense to compare the velocities of a lighter weight bullet with a heavier one, as you have done, you're talking apples and oranges.

I do not see a load in any of my references for a 168 grain bullet that will reach 2,800 fps safely and consistently. I'm sure one could work up to that for a given load, but doing so would be at your own risk and, in my opinion, unnecessary.
