9mm Defensive Load Barrier Tests!
This 9mm defensive load barrier test evaluated Underwood Xtreme Defender, Hornady Critical Duty, Speer Gold Dot, and Federal HST through drywall, wood, and sheet metal into ballistic gelatin. The Underwood Xtreme Defender consistently performed best, maintaining expansion and penetration. Traditional hollow points like Gold Dot and HST struggled with expansion and over-penetration after encountering hard barriers, often plugging with debris.
