Lehigh Defense’s .30-cal., 145-gr. Controlled Chaos (CC) bullet is an all-brass, hollow-point projectile with performance similar to the Nosler Partition; during penetration the front portion is shed (catastrophically in this case, causing extreme damage to vital organs) while the base penetrates deeply. As I observed during Alberta’s 2014 spring black bear season, this modern projectile indeed maximizes the potential of the .30-’06 Sprg.
