BulletBud,
What bullet weight, cartridge and velocity?
During a cull hunt I tried to get a 168-grain Hunting VLD to "blow up." The cartridge was the .30-06, muzzle velocity 2800+ fps. Had just killed a feral billy goat weighing around 180-200 pounds, and shot one of the bullets into the big shoulder joint from maybe 10 feet away. The bullet broke the joint and penetrated well into the chest cavity.
