This new option brings the same painstaking attention-to-detail found in the company's bullets to an entire cartridge. Each round in the Sierra Ammunition GameChanger lineup is topped with the company's proven projectiles, guaranteed to provide a hard-hitting, bone-crushing projectile to drop game where it stands. In addition, each round is finely calibrated to ensure that bullets end up exactly where shooters want them. Mfg: Sierra Bullets
