This test compares Lehigh Defense's 90-grain Xtreme Defense 9mm bullet with and without flutes. The fluted version demonstrated superior energy transfer, dumping all its energy within 18 inches of ballistic gel. The non-fluted variant over-penetrated, highlighting the critical role of flutes in controlled terminal performance for defensive ammunition.

This video from Lehigh Defense and Wilson Combat demonstrates the performance of their 9mm 90-grain Xtreme Defense bullet using FBI-calibrated gelatin. The test compares a bullet with their Fluid Transfer Monolithic (FTM) flutes against one without, highlighting the flutes' role in creating a significant energy dump and controlled penetration of 18 inches. A high-speed camera at 4000 fps captures the wound cavity. The description emphasizes the advanced monolithic copper construction and its ability to create a large permanent wound cavity, outperforming traditional hollow points, especially after barrier penetration.
