This video explores the extreme velocity potential of the .17-5.56 KAK wildcat cartridge, achieving over 5,200 FPS, nearly 1 mile per second. Testing reveals its devastating effect on targets like watermelons and ballistic gel due to rapid fragmentation and temporary wound cavity expansion. While it penetrates Level 3A body armor, it is stopped by Level 4 ceramic plates.
