Product Description Winchester Ammo Unprimed Rifle Shellcases are engineered to precise tolerances to help deliver smooth-feeding and positive chambering for dependable reloading performance. These unprimed .223 Remington brass cases are a solid choice for reloaders who want consistent components for building custom loads. During manufacturing, cases are annealed to achieve the correct hardness for secure bullet retention while still providing flexibility during firing; as a result, cases may show a light stain near the neck. As with many new cases, mouths may require standard reloading prep such as resizing, chamfering, and deburring before use.
