I guess one thing that bears discussing here is the distance being shot. I became a huge fan of the high shoulder shot after I started extending the ranges I shoot. The first advantage is that it allows for a fairly wide margain of error. In fact, it's a hard shot to screw up, other than completely missing which is much preferable to a non fatal hit. Second, the results are typically a drop on the spot response. This is important when shooting long ranges as it can take a fair amount of time to get to the scene of a hit when you have to walk a 1/2 kilometer or more. Even finding exactly where the animal was standing can be a challenge if there is no snow so walking to an animal that dropped on the spot is preferable. Anyhow, that's why I'm a fan of the high shoulder.
