Hornady Custom Grade Features The seating stem inside this die is machined to match the ogive profile of specific 25 caliber bullets rather than using a generic one-size-fits-all seating surface which means bullets seat concentrically and without the crushed tips or deformed jackets that a poorly matched stem can cause. This precision fit matters most with polymer-tipped match bullets like the Hornady ELD-X where even minor seating damage can throw off ballistic coefficient and downrange accuracy. Reloaders chasing tight repeatable groups benefit directly from a stem cut to their exact bullet profile rather than approximating it. Because this die is engineered exclusively for Hornady Custom Grade Die bodies it will not thread or seat correctly in dies from other manufacturers so reloaders need to confirm they re running a complete Hornady Custom Grade set before adding this stem to their kit. This makes the die a natural upgrade or replacement part for handloaders already invested in Hornady s Custom Grade reloading system rather than a standalone universal tool. Precision rifle shooters and hunters loading their own 25 caliber ammunition around bullets like the 135 grain ELD-X will get the most out of this dedicated bullet-specific seating stem.
