Forster Neck Reamer #224 (.224 Diameter) – NR1224 Case Prep

Description

If you've been chasing flyers on the target and can't figure out where they're coming from, inconsistent neck wall thickness is often the culprit. The Forster Neck Reamer #224 is a straightforward fix for that problem, cleaning up the inside of your case necks so brass thickness stays uniform from one piece to the next. It's cut for .224 diameter bullets, which covers a big chunk of the popular varmint and target rounds a lot of folks are loading these days.

How the #224 Neck Reamer Works

This reamer drops into the cutter of a Forster Case Trimmer in place of the pilot, so if you already own one of their trimmers you're ready to go. It shaves excess brass off the inside walls of the neck, which keeps bullet grip consistent and helps bring chamber pressures back into a predictable range. Standard reamers like this one are ground .0025 to .003 inches larger than the maximum bullet diameter, and on the #224 that works out to roughly a .2265 inch cutting diameter. That slight oversize is intentional and gives your bullets a proper fit once the neck is sized back down.

Built to Cut Clean

Forster machines these from high-grade, wear-resistant tool steel, so the cutting edges hold up over a long reloading career. The staggered tooth design is the detail that really matters here, because it slices through brass smoothly instead of grabbing and chattering the way a lesser tool would. That translates to a cleaner finish on the inside of the neck and less fuss at the bench.

Fitting the Reamer Into Your Routine

Timing matters with a neck reamer. Standard reamers are meant to be used after a case has been fired with a full load and before the neck or full-length sizing step. The simple rule of thumb worth remembering is to ream after firing, or turn after sizing. Handle it that way and the #224 becomes a quiet, reliable part of your prep process that keeps your match brass and your hunting loads performing the way they should.
