Overview – What It Is
The Lock-N-Load AP is a 5-station progressive press that focuses on quick caliber changes, automatic priming, and efficient high-volume reloading. It is built for reloaders who need speed without sacrificing precision, making it suitable for pistol and rifle cartridges. If you are upgrading from a single-stage or turret press and want to produce hundreds of rounds per hour, this setup delivers consistent results with minimal downtime.
What is in the Box
Typical contents (may vary by batch/region):
- Lock-N-Load AP press frame with 5-station tool head.
- EZject system for case ejection.
- Automatic priming system (includes primer feed tube, shuttle, and seater punch).
- Operating handle with ball knob.
- Large capacity cartridge catcher.
- Printed instructions and basic hardware.
Usually not included: shell plates, dies, case feeder, powder measure (available in kits like the Ammo Plant), bench mounting bolts.
Materials & Build
- Frame – thick cast aluminum with red powder-coat finish for durability and resistance to wear.
- Ram – steel construction with smooth, spring-loaded operation; supports automatic indexing.
- Linkage & Pins – heavy-duty steel arms; includes grease zerks for easy maintenance.
- Handle – robust with comfortable ball knob; provides consistent leverage.
- Finish – powder coat and machined surfaces resist corrosion from powders and primers; tight tolerances for reliable cycling.
The 5-station design with Lock-N-Load bushings allows for rapid die swaps while maintaining alignment. Though not as rigid as some cast-iron competitors for extreme tasks, it handles standard progressive workflows with smooth, half-stage indexing on both up and down strokes, reducing jams and improving feel.
Key Specs & Compatibility
- Stations: 5 (allows dedicated stations for sizing, expanding, powder drop, seating, crimping).
- Die threads: 7/8″-14 (standard; compatible with most dies).
- Shell plates: quick-change Lock-N-Load style; required for each caliber.
- Stroke / capacity: handles pistol (e.g., 9mm, .45 ACP) and rifle (e.g., .223 Rem, .308 Win) up to 3.3″ overall length; outputs up to 500 rounds per hour with practice.
- Priming: automatic system with easy swap for small/large primers; case-activated powder drop.
- Mounting: bench mount with three holes; compatible with quick-change plates and accessories like case feeders.
Warranty & Origin
Manufacturer: Hornady Manufacturing, Inc. (USA). Components are primarily made in the USA with some global sourcing. Warranty is a lifetime limited warranty against defects in materials and workmanship under normal use; contact Hornady with proof of purchase for details.
Where the Lock-N-Load AP Excels – Use Cases
- High-volume pistol loading – 9mm, .40 S&W, .45 ACP: fast cycling and case-activated features minimize errors.
- Rifle ammo production – .223 Rem, 5.56 NATO, .308 Win: precise powder drops for consistent velocities (extreme spreads under 20 fps with tuned setup).
- Quick caliber swaps – change from pistol to rifle in under 5 minutes with preset bushings; ideal for multi-caliber reloaders.
- Ammo plant configurations – add case and bullet feeders for near-automated operation on large batches.
- Beginner-to-intermediate upgrades – intuitive for those new to progressives, with room for advanced tweaks like micrometer adjustments.
Setup & Mounting – Do It Once, Do It Right
- Bench: sturdy surface (e.g., 2″ thick wood or metal); use Grade 8 bolts with washers for secure mounting.
- Placement: position for full handle swing; align over bench support to avoid flex.
- Indexing: adjust automatic half-stage indexing for smooth operation; calibrate per manual.
- Priming system: swap tubes and punches for primer size; ensure feed path is clear.
- Die installation: insert bushings with a twist; lock dies with Sure-Loc rings and verify alignment with a test case.
- Accessories: add primer catcher and cartridge bin; lubricate zerks lightly with grease.
Real-World Notes
- Smooth indexing reduces operator fatigue and jams compared to full-downstroke designs.
- EZject system reliably ejects cases without tweaks, keeping the bench clean.
- Case-activated powder drop prevents spills; quick metering inserts speed powder changes.
- For high precision, pair with micrometer dies; users report sub-MOA groups with tuned rifle loads.
- Initial setup may take time for beginners, but once dialed in, it runs consistently for thousands of rounds.
