Product Overview

This collet is required for a reloader using the Forster Original or Power Case trimmer that needs to trim any of the below cartridges.

Notes: For cartridges not listed, use the case's base size to determine the correct collet. For example, for a 35 Whelen, it has a 30-06 Springfield base case size. Most reloading manuals will list the original case for Wildcat and other odd cartridges

  • This collet will not work with Classic Case Trimmer
  • Use of this collet requires collet housing opening to be enlarged on some Forster trimmers. Forster will do this at no charge. If this collet will not fit in collet housing, ship housing only, not entire trimmer to Forster. This modification will not affect the use of other collets.
