I fail to understand the trend to super heavy bullets at low low speed. Indeed, this seems to me like reinventing the 12gage slug. Compare weight and speed!
Looks to me more like fashion than science. Yesterday it was super high speed and the mythical shock wave, now it is just the other way around.
By the way, a slow slug is more likely to bounce and therefore less safe. This is a fact with 12g slug.
The truth seems to be in the middle.
