The Forster Neck Reamer in .224 caliber (Forster part no. NR1224) is a precision hand tool for handloaders who trim and true fired brass before reloading. Rather than fitting a trimmer’s pilot, this reamer chucks directly into a case trimmer to grind the inside of the case neck to a true, consistent .224 bore diameter. A neck left too thick after repeated firings can pinch the chamber and send flyers downrange; reaming it back to spec restores clean bullet release and consistent neck tension. It’s a small, inexpensive fix for a problem that otherwise shows up as unexplained accuracy loss at the bench.

Key Specifications

• Bore diameter of .224. Matches the neck reamer to the specific caliber being trimmed, so every case comes out to the same true internal diameter.
• Chucks into a case trimmer, not the trimmer pilot, so the reamer follows the case mouth rather than the bullet seating path.
• Machined from durable tool steel for repeated use across many reloading sessions without losing its edge.
• Built for unsized, untrimmed fired cases, grinding the full neck diameter to precision before the case goes back into the sizing die.
• Weighs about 0.3 oz, light enough to store in a small compartment of a reloading bench drawer.

Frequently Asked Questions

What is a neck reamer used for? It removes excess brass from the inside of a fired case neck so the neck wall is a uniform, true thickness before the case is resized and reloaded.

Does it fit in a standard case trimmer? Yes, this reamer is designed to chuck into a case trimmer rather than mount on the pilot, so it works alongside your existing trimming setup.

What caliber is this reamer sized for? This is the .224 caliber reamer; Forster offers the same reamer in other common diameters for handloaders working multiple cartridges.
