The ED penetrates hard barriers better than jhp.
The Extreme Penetrator would ALSO be used against larger predators because of the increased penetration. The EP does not produce as large of a wound channel as does the ED but penetrates much deeper.
Therein lies my reasoning for my choice to use 9mm and .45 ACP Penetrators as truck backup and possibly 3rd mag backup for barrier penetration (car doors, fenders, sheet metal, etc) and defense against large predators... The 2-legged kind, that is.
