Full Length Sizing Dies

Full_Length_Sizing_DieUse after each firing or after several firings, when the resulting brass flow will require the case to be full-length sized. Allows case to be re-chambered in any SAAMI rifle chamber with minimal play.

Full Length Sizing Die Instructions


  • Sizes the case neck, shoulder and body and expands the neck and removes the spent primer.
  • Precisely-positioned vent hole located in the threaded or recessed portion of the die body prevents excessive, trapped air and/or lubrications from damaging the die’s components or your cases.

Note: For use on military brass with crimped primers, use a decapping die first to remove spent primer (not available from Forster Products).CutawayDie_FLS_thm

We can custom hone the inside neck diameter of our Full Length Sizing Dies and Neck Sizing Dies. Custom honing is a diamond stoning process that enlarges the inside diameter of the die and will prevent over-sizing of the case neck due to thick neck walls. You may need this service for two reasons:

  • If you use some brands of brass cases, such as Norma or Lapua, which have thicker neck walls.
  • If you do not intend to outside neck turn case necks that have thickened after repeated firings.

Full Length Sizing Dies are available in more than 70 calibers, either individually or as a set with our Bench Rest Seater die.
