FWIW, I thought I would use Berger 6mm 105 grain target hybrids for hunting whitetail using a 6mm Remington AI, muzzel velocity was 3050 fps.
Placed some plastic 1 gallon milk jugs filled with water at 100 and 500 yards and shot them to make sure that the target bullet would show some expansion.
At 100 yards the jug was ripped apart with a very impressive spray of water.
At 500 yards the bullets penciled thru, no destruction of the jug, just little entry and exit holes. Did not even tip the jug over, leading me to believe the bullet expanded little to none.
They are accurate bullets with an impressive BC but I would not shoot game with them. I do not see any hybrid bullets listed on Berger's site for hunting.
