Is "Good Enough", Good Enough?...Black Hills .40 S&W Self-Defense AMMO Ballistic Gel Test!
This video presents a ballistic gel test of Black Hills Ammunition's 155-grain JHP .40 S&W self-defense rounds. The instructor, with apparent experience in firearms testing, evaluates performance from both a Glock 27 (3.5-inch barrel) and a Glock 22 (4.5-inch barrel). While not top-tier, the ammunition demonstrated adequate expansion and penetration, particularly from the longer barrel, suggesting it's a viable option for concealed carry or self-defense.
