My son and I have shot a pile of deer with Barnes. 25-05 with 115 gr, 7-08 with 120ttsx, 270wsm with 140 and 110 TTSX. We love the way they perform. No need to aim for bone, etc. Shoot them like any other bullet. Sometimes they go 30-50 yds, but easy to find, and other times drop in their tracks. I love the fact that I can shoot them at any angle and know that I will get the penetration I need. Your experience sounds like the bullet did a great job, 30 yds and died. No bullet will drop them in their tracks everytime.Shot a medium sized doe Friday with my .257 Weatherby Mag and the Barnes 100gr TTSX bullet. Was my first time using a Barnes bullet. Picture perfect heart lung broadside shot at 275 yards. The doe walked off and went about 30 yards into the woods, laid down and died. The blood trail was not impressive at all, the bullet did go through but the exit hole was not much bigger than the entry hole. I was surprised, the week before I shot a nice 8 point with a .308 and 125gr Hornady SST bullet that was much more devastating, massive blood trail and only took a few steps. Not sure I am sold on Barnes bullets, My bullets of choice (Accubond) are all sold out so I thought I would try these Barnes, so far not impressed. I will try a few more.
