RE: I want an explosive bullet when it hits the deer!
I have been using BT for a long time. 30-02, 270, 243. Nosler BT, Hornday SST, Winchester Ballistic Siver Tips. All bring down deer and hogs in a few paces. As alot have said, the key is a good shot. I had a quartering away shot. Blew the hind quarter away, but found out that my scope was broken and wouldn't hold a zero sitting in the case! Not the bullets falt, it was all me!! You can't get much more explosive than the BT. Also, I've shot nothing more accurate in factory loads.
When you go with Boat Tails or Patitions, you need more pressure to expand (more meat or bone). Save those for really big deer, moose, elk, etc.
Just my opinion, but its based on experience and alot of reading.
