Hornady High Speed Trim Collet - Small Rifle/Arc

The Hornady High Speed Trim Collet is a replacement collet designed for use with the Hornady High Speed Case Trimmer. Sized for Small Rifle cartridges, this collet securely holds small rifle case necks in proper alignment during the trimming process so the cutter can square case mouths to a consistent, uniform length for reliable handloading.

Hornady collets are precision-machined to grip the case neck without distorting the shoulder or body, keeping case concentricity true while the trimming cutter does its work. The Small Rifle/Arc sizing covers common bottlenecked rifle case diameters in the small-rifle range, making this a useful replacement or dedicated spare for handloaders running high volumes of small-rifle brass through their Hornady trimmer.

Whether you are replacing a worn original or setting up a dedicated collet for a specific small rifle cartridge, the Hornady 480302 is the correct factory part. Drop it into your Hornady high speed trimmer and you are back to trimming cases to uniform length and square mouths, ready for resizing and reloading.
