Right now my #1 "Go to" bullet is the 200 grain Shockwave/SST. It just has been a great all-around bullet for me, and does many things well. Here is a pic of the only one I've ever recovered from a deer (it was shot head on, facing me, bullet found in rear ham).
Having said that, I like to experiment with bullets a lot, so my "go to" bullet may well be different a couple years from now. I also like the 185 Lehigh and the .452 250 grain Deep Curl....
