Winchester VarmintX Centerfire Rifle Ammo utilizes a polymer tip over a copper-jacketed, lead-core bullet to deliver explosive expansion on varmints and predators over a wide range of distances and impact velocities. The bullet's polymer tip and aerodynamic profile increase ballistic coefficient to flatten trajectory and reduce wind drift, making it highly effective for predator hunting at long-range. VarmintX Centerfire Rifle Ammo is manufactured under tight quality control and loaded with premium components to ensure reliable function and consistent velocities. Reloadable brass cases
