The .38 Special Super Police load featured a blunt round nose bullet weighing in at 200 grains, with a nominal velocity of 700 fps from a four-inch barreled revolver. It was more effective against soft targets than the standard 158-grain load, but less effective against vehicles.
What I didn’t know then about the 200-grain Super Police bullet is that when it hits soft tissue, it consistently yaws. The “long for caliber” slug at moderate velocity is on the edge of instability in flight. This causes it to begin to turn sideways as it moves through soft tissue, causing a PERMANENT wound path and exit that ends up being much larger than the entrance hole. A bullet that yaws increases trauma and reduces over-penetration, without the cost, blast, and heavier recoil of modern +P hollow point defensive ammo. If the original Super Police bullets really did yaw when hitting soft test medium, I would consider carrying them in my Smith & Wesson Model 642. However, I couldn’t find original .38 Super Police ammo anywhere! Fortunately GAD Custom Cartridges of Medford, Wisconsin was able and willing to replicate the original loads.

I'd never heard of this cartridge before. Sounds very interesting.
