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. Full Metal Jacket bullets are designed for positive functioning and good accuracy with no expansion and little or no barrel leading. Perfect for low-cost target practice. This is not loaded ammunition. Note:The 35 Caliber 145 grain bullets are specifically developed for the 350 Legend cartridge. Many other bullets with similar diameters simply do not work in 350 Legend and subsequently reloaders are having issues with those components. These bullets will eliminate those issues and allow handloading of the 350 Legend.
