Neck Reamers

Thick case necks can cause high chamber pressures and flyers. The Forster Neck Reamer mounts in the cutter of a Forster Case Trimmer in place of the pilot and removes the excess brass from the neck walls with tool-steel blades.

The Neck Reamer is manufactured from high-grade, wear-resistant tool steel and ground .0025″ to .003″ over the maximum bullet diameter. The staggered tooth design cuts the brass smoothly without chattering.

Also keep in mind when using your Forster Neck Reamer:

  • Neck reaming should be performed only after the cases have been fired with a full load and before the neck or full-length sizing operation.
  • Wall thickness can be measured with a tubing micrometer, but a simpler test for excess brass in the neck area is to slide a bullet into a fired, unsized case neck. If you feel interference, the neck should be reamed or outside neck turned.
  • Use neck reamers before resizing. Exceptions to this rule are:
    • NR1220 – .220″ diameter reamer for .224″ bullets
    • NR1239 – .239″ diameter reamer for .243″ bullets

    These are common sizes that reloaders use to ream their cases just before seating bullets. These three sizes are kept in stock for those who intend to ream after the sizing operation just before seating bullets.

    Wildcatters often require specially sized reamers when converting brass from one caliber to another.
