Lehigh Defense Controlled Fracturing bullets in .451 Caliber, 170 grains (brand part no. 02451170SP), are a monolithic copper bullet engineered to fracture into multiple wound channels on impact, bullets built for self-defense and hunting handgun loads. Sold 50 per box, these are component bullets for handloaders who want to build their own .451 Caliber ammunition rather than buy factory loads. Lehigh Defense’s reputation in this bullet line comes down to consistent weight and dimensional tolerances from bullet to bullet, which is what lets a handloader actually realize the accuracy a well-built rifle or pistol is capable of.
