huntnshoot. The bullets I saw fail were early ones. I don't see a difference in the newer or older designs. If the new ones work so wonderfully, why did Nosler make the Accubond with the thicker jacket? The Accubonds work well, as do the Partitions. I however like Barnes X bullets. No jacket or core to separate. I just prefer not to use BT's on anything but paper. Ignore away!
