Hope he at least gets to make a bear rug
Nope.
When Wildlife officials show up they confiscate the carcass.
They will take varied measurements, skull, tooth, and paw size.
Depending on the species and circumstance it may be harvested for meat.
Most times it will be professionally skinned.
The departments have annual auctions, if this guy wants the hide he will have to bid on it.
.40, I would say a “High capacity” magazine and keep going until success or flight.
Despite that I do know of an Alaskan native woman (PC enough?) who killed a Grizzly with a single .22LR shot.
Right through its open mouth and the soft upper palate into the brain.
I would never want to try to duplicate that shot.
