Here is a bit more info on Berger bullets expansion
Our tests have indicated that we have been able to confirm as low as 1,800 fps and still get the three to five inches of penetration and then the aggressive expansion of the bullet. The following article link of http://www.bergerbullets.com/article...er-bullets.pdf will take you to an article written by John Barsness from when he had accompanied us to New Zealand for detailed testing of our Match Hunting VLD bullets. This is an interesting article that many shooters have found to be very informative. We hope this will as informative for you, and the others!
Cordially,
