I've done a little informal testing with the 64gr Nosler here are my results.
Group fired at 100 yards from a 1-8" twist NULA .223 MV 3100fps
Here is a bullet I fired into milk jugs full of water at 10 yards MV 3100. The bullet was found in the forth jug where it ruptured but didn't enter the fifth jug.
Will Munny: It's a hell of a thing, killing a man. Take away all he's got and all he's ever gonna have.
The Schofield Kid: Yeah, well, I guess they had it coming.
