MARK II DB Case Annealer with Touchscreen
AMP Annealing Made Perfect MARK II DB enables precise and repeatable case annealing by induction—without open flame or guesswork. The case neck is intensely heated, altering the metal’s microstructure to make the brass less brittle and more reusable. The integrated AZTEC analysis function detects the case material structure and automatically determines the optimal annealing time and power. This ensures consistent results and controlled restoration to a defined hardness level.
Key Advantages at a Glance
- Induction annealing – precise, clean, repeatable
- AZTEC mode automatically determines the optimal program
- Quick caliber changes
- No manual calibration required
- Touchscreen operation with intuitive menu
- USB-C port for easy software updates
- Compatible with all common calibers from .17 Hornet to .50 BMG
- Stable footing with adjustable legs
- High repeatability – ideal for precision reloading
Automatic Calibration with AZTEC Analysis
Instead of manual fine-tuning, a reference case is analyzed—annealed at maximum power until destroyed. Based on the data, the MARK II DB automatically generates a code for a matching annealing program. This process is repeatable, brand-independent, and reliable even when switching lots or calibers.
Features and Technology
A capacitive touchscreen enables straightforward navigation. USB-C connectivity allows quick and easy software updates. The device supports calibers from .17 Hornet to .50 BMG. With separately available pilots and case holders, each case is safely guided. Adjustable feet provide stability, even on uneven surfaces.

Induction Case Annealing – Learn More
During induction annealing, the shoulder of the brass case is selectively heated to make it softer and more flexible again. Repeated firing and resizing cause the material to become hard and brittle, increasing the risk of cracking. Annealing relieves internal stress and restores the brass’s flexibility. Induction heating generates highly precise and uniform heat via an electromagnetic field, targeting only the desired part of the case—typically reaching about 343 to 371°C (650 to 700°F). The process only takes a few seconds and ensures the brass remains durable and reliable for your next reloading session.
