Rost,
You are correct, there is more to the equation then just speed. When I say "speed kills", I'm thinking of real speed with a real bullet.
One of my favorite combinations is a 160gr Nosler Accubond leaving my 7mm STW around 3400. So I have bullet that will violently open up, yet hold together to make deep holes. In the real world with wind and critter that have a mind of there own, placement is not always perfect, but the increased destruction does increase your acceptable margin of error, and what could of been a chase can be turned into a critter that isn't going any where. I do get more DRT's with this combination, but IMO that largely due to a higher probability that I will damage/shock the CNS with the larger wound cavity.
