Hornady Neck Size Reloading Die is an effective, precise way to perfectly size your cases for hand-loading. Neck sizing with this Hornady reloading tool can eliminate problems of excessive head space, and align the bullet perfectly with the bore, resulting in better accuracy and longer case life. Articulated details on the reloading die offer more precise reloading, by offering easier adjustments, better alignment and smoother functioning. The internal die profile of the Hornady Elliptical Expander Neck Sizing Die is precision machined and polished to a smooth finish that delivers reliable functioning without case sticking or excessive friction, and Hornady has equipped the die with their patented Zip Spindle design, which positively locks to eliminate slippage. An integrated elliptical expander also eliminates the need for a separate expander die for necking-up to the next caliber. For sizing cartridges for your bolt-action rifle, you’d do well to choose the Hornady Universal Neck Sizer Die.
