It's not that it's so bad, but more about it's a marginal round to use and people don't confine their shot opportunities to it's limited range. Instead through the heat of the excitement, they see a deer at like 65 yards and pull the trigger. At that range, they may get lucky... or not.

It's deadly, but you have to keep your shots close and know your weapon's shot pattern so you know what you can and can not get away with.
