Yeah, "premium" bullets tend to penetrate deeper when driven faster.
The occasional exceptions are those that open much wider at higher impact velocities. Some of the bonded-core bullets with no mechanism in the jacket to limit expansion will open so widely penetration is less. I have seen this a number of times, and for the same reason cup-and-core bullets often penetrate less at higher velocities.
But bullets like the TSX, E-Tip, GMX, Partition, North Fork, Trophy Bonded, etc., where expansion is stopped at a certain point in the shank tend to penetrate deeper when driven faster.
