The Bastard Child Of 9mm And .357 Mag: HSM 125 gr UHP Gel Test

The Speer Uni-Cor is a fantastic projectile but HSM is known for sometimes producing light loads. Then again, .357 mag is pretty rowdy and rather forgiving in regard to terminal effect. We shoot HSM's .357 mag 125gr Uni-Cor from a Smith & Wesson Model 13L 4" revolver into clear gel to assess terminal performance.
