Varmint Express rimfire ammunition is specifically designed for supremely accurate long-range shooting. Loaded with an XTP bullet, each round features a performance-improved point that has six (6) precise folds to divide the bullet into symmetrical sections and initiate controlled expansion at low velocities while not fragmenting at higher velocities. They expand reliably at a wide range of velocities for a deep, terminal penetration with every shot. The XTP bullet has a swaged core and drawn copper jacket to ensure uniform expansion and in-flight stability. This ammunition is new production.
