Great bullet testing! I love it. Two very different results and an overall very interesting test! Those hornady's blow up well as that is what they were designed to do. The bergers very disappointing. I wonder what theyd do with more velocity. Its all in the hydrostatic shock i believe. Out of my little cva 243 i use tipped barnes or scirroco's. The tips make em open well at pistol velocities but hold together well when the game gets bigger. Im not afraid of an a max on deer though!
