Winchester reloading components are the same that are used in Winchester ammunition. Winchester puts their components through very tedious and strict quality control to provide the best product available at an extreme value. From plinking to big game hunting, there is sure to be a Winchester component to meet your needs. Silvertip offers a unique combination of power, precision, reliable functioning and on-target performance via a specially engineered jacketed bullet. This bullet delivers penetration and rapid energy release with virtually no weight loss or bullet fragmentation. This is not loaded ammunition.
