I have now shot a 6x6 bull at 600 yards and a 4x4 buck at 300 yards and on both animals i was not happy with how my 210 grain hunting berger bullet preformed. In both cases the bullet peirced through and I ended up shooting multiple times to kill the animals. All shots where placed right behind the front shoulder. I have never had this problem with Accubonds, in fact i have never had to shoot more than once to kill an animal. The exit wound was tiny like there was no expansion. I was just curious if anyone else has had this problem. I wish i had better luck with these because they sure shoot good.
