On two occasions, both on moose, with a 7 RM and 300 WM, lighter bullets at very close range, so traveling fast at impact... the front half "splashed" and the rear half took a very unexpected and in the case of the 7 RM, unexplainable weird and divergent route, given the shot angle and body posture. The .300 WM hit the scapula square and splashed and then the rear half angled forward and exited at the base of the neck, the follow-up was a couple minutes later at approximately 100 yards and worked perfectly through broadside lungs. The 7 RM went between ribs, broadside at 20 yards, the front half splashed and the rear made an inexplicable, turn/tumble through the liver and into the paunch, what would have been almost right angle, well, say 70 degrees to the flight path, and the entrance did not contact the rib... the follow-up through the neck put it down at about 50 yards. In my estimation, neither wound paths should have occurred as they did, momentum being what it is (?). I chalked it up to a bullet too light and fast for the close range, even though the two part design is suppose to compensate for exactly that scenario, it apparently does not do that perfectly in all circumstances. I still am a big fan of Partition bullets and use them alot in many calibers and weights, but not in my barn-burners.
