What do you do if you don’t feel that a 12-gauge slug doesn’t have enough stopping power? OK, so maybe if you ever feel under gunned with a shottie slug you’re fighting Godzilla, but, hey, it could happen. You could try to stuff a 40mm grenade in there, but that requires all sorts of complicated licensing. A more realistic option might be to use a fragmenting projectile design. That’s exactly what Winchester Ammunition has done with their PDX1 Defender Segmenting Slug.
The PDX1 Defender brand umbrella covers a lot of territory. Early on, the line was comprised of a range of bonded pistol ammunition. Designed to expand reliably and retain its mass through tough barriers, it quickly gained a reputation for consistent performance across a wide range of handgun calibers. Over time, the PDX1 Defender family has expanded into rifle calibers and a series of innovative shotgun loads. For example, it’s the PDX1 Defender line that offers a .410 shotshell with a combination of disks and buckshot. Another load combines a slug with buckshot pellets. This one is all slug, but with a twist.
The theory of the Segmented Slug is that shortly after penetrating an organic target, the one-ounce slug will separate into three equal fragments. Each will veer off course to create it’s own separate wound channel. You get the impact of a one-ounce slug with the internal wounding capacity of three separate projectiles.
Let’s do some quick math on this. A one-ounce lead slug weighs 437.5 grains, or about the same as three heavy 9mm or light .40 S&W bullets. Think about that. Once the slug penetrates a few inches, it transforms into three handgun-sized projectiles, each plotting its own course through the target.
