Any experience with expansion of 7mm 180vld's at ~2800fps on game.
It would appear that all Berger VLD's need an impact velocity of about 1,800 ft/sec to ensure reliable expansion. Some expansion takes place at lower velocities but it may be highly reliant on the impact surface.
Muzzle velocity is largely irrelevant.
