Largest Expanding 9mm Bullet?
The Norma MHP 9mm Luger 108-grain load demonstrates impressive expansion in ballistic gel, reaching .900 inches with 100% weight retention and 11 inches of penetration. However, it failed to expand when fired through barriers like drywall and automotive glass, acting more like a solid projectile. This makes it a potentially good option for civilian self-defense where over-penetration is a concern, but less suitable for law enforcement barrier penetration needs.
