Product Overview

Keep your Hornady Lock-N-Load AP press running smoothly with the genuine Hornady 398359 Primer Follower – the small part that makes a big difference to reliable priming.

Designed specifically for the Lock-N-Load AP auto priming system, this factory replacement follower sits on top of the primers in the tube to maintain consistent pressure and feed. That means fewer interruptions, fewer misfeeds, and more time actually loading ammo. Because it’s a Hornady original spare, it matches the dimensions and fit of the OEM part, dropping straight into your existing primer tube assembly with no modification required.

Whether you’re replacing a worn or lost follower, or simply building a spares kit for your progressive press, the 398359 Primer Follower helps ensure smooth, predictable primer delivery on every stroke. Pair it with genuine Hornady primer tubes and pick-up tubes to keep your Lock-N-Load AP press operating at its best session after session.
