Winchester Ammunition is bringing a new line of self defense ammo to the market in 2009: the Bonded PDX1 Personal Protection Ammunition.
The PDX1 Personal Protection Ammunition is “engineered to maximize terminal ballistics, as defined by the demanding FBI test protocol, which simulates real-world threats.” While I believe the protocol is a useful tool to make a side-by-side comparisons of different cartridges and bullet designs, I do not believe that it simulates “real world threats” for the vast majority of people who own firearms for self defense.
