The 180 game king I caught from my weatherby was a big buck. The core was loose but with the jacket. The 35 Game king I caught from my Whelen went lengthwise through a grown buck and was a perfect mushroom. The 30 165 gn CoreLokt I caught this year was a perfect mushroom just like the Remington commercials too. The 243 bullets I caught maybe 2 of them the jacket held the core the rest were blown up and separated. The deer died though. That was the goal.
I do like bullets to blow a hole through to bleed out of. Makes the ones that run easier to find.
