Optimize your reloading precision with the Hornady neck sizing die. Designed to eliminate excessive headspace, this die aligns the bullet perfectly with the bore, resulting in improved accuracy and extended case life. Ideal for bolt-action rifle cases, it enhances performance by reducing wear and ensuring a seamless fit. However, for auto-loading, lever, and pump-action rifles, full-length resizing is recommended. Before use, it's important to thoroughly clean the die to remove the factory-applied rust preventative - Hornady one shot cleaner and dry lube or any commercial solvent will do the job. Proper lubrication of case necks inside and out is essential for optimal resizing. Adjusting the die is easy: simply thread it in quarter-turn increments while lowering the ram to inspect the case neck until it's perfectly sized. Be cautious not to over-tighten the die, as excessive pressure can cause the case to buckle. Once adjusted, lock the die in place, and reinstall the Expander/Decap Assembly, ensuring the decap pin just touches the shell holder. The Hornady Neck Sizing Die ensures a precise and efficient resizing experience for superior performance. Design of the zip spindle Polished surface
