APW - Expander Mandrel Set (Standard / Deluxe TiN)

Category RELOADING

Two takes on the same purpose: stabilize neck tension via mandrels to improve consistency. The standard set covers the fundamentals (die body + mandrels + holder), while the Deluxe version adds TiN-coated mandrels to reduce friction and boost durability, aiming for smoother, more repeatable sizing as stated by the manufacturer.

Use / positioning
Reloading tool described as smoothing and gently expanding the case neck to ensure consistent neck tension. The manufacturer links this approach to a straightforward way to significantly reduce Extreme Spread (ES) and Standard Deviation (SD).

Standard set: contents & concept (manufacturer)

  • Interchangeable mandrels described as “precisely sized”

  • Mandrels for achieving 0.001 or 0.002 neck tension

  • Included base for organization/storage

Standard set: included mandrels (manufacturer)

Deluxe set: TiN features & tolerance note (manufacturer)

  • Titanium Nitride (TiN) coated mandrels: described as wear-resistant, inert, and providing notable friction reduction

  • Stated benefit: reduced friction between mandrel and case neck → smoother, more consistent resizing; contributes to consistent neck tension and overall reloading precision

  • Manufacturer note: slight sizing variance may occur due to TiN coating “thickness”; regular in-process QC is stated to meet tolerances
