I have never used Berger bullets for any big game hunting but I have a friend that used them while hunting mule deer and he did not like them for "fragging" up. I myself will continue to use Nosler Partitions, TBBC or Swift A Frame bullets on my big game animals. Nosler Accubond is a great long range bullet! It has stayed together on the wet news print test we have done at the farm. The B.C. and S.D. are very good on this bullet.
