With their extra-long boattail design, these bullets produce a high ballistic coefficiency value that's ideal for long-range hunting. Each 100% copper, lead-free round is topped with a polymer tip that initiates expansion creating four deadly cutting petals. Even at long range, these rounds produce deep penetration while retaining virtually 100% of their weight. Multiple rings cut in the shank relieve pressure and virtually eliminate copper fouling.
