Underwood Controlled Chaos ammunition in 7.62x39mm (part no. 568) loads a 123-grain fragmenting bullet at a listed 2,450 feet per second, a Lehigh Defense design built to do more than simply expand on impact. Controlled Chaos is engineered so the bullet’s nose fractures into several sharp copper petals immediately on impact, each petal cutting its own wound channel while a solid rear shank continues driving forward for deep penetration. That combination of fragmentation and penetration is a different terminal mechanism than a standard expanding hollow point. For AK-platform and SKS shooters who want maximum terminal effect from 7.62x39mm, this rifle ammunition is engineered for that job.
