The Forster Products 0.2265" inside neck reamer is a precision reloading tool designed for handloaders who want consistent, tight neck fit on their rifle ammunition. This carbide-cutting reamer removes excess brass buildup from inside the case neck—a common issue that develops over multiple firings and can cause erratic seating and alignment problems. If you're getting resistance when seating bullets into fired cases, or if a bullet doesn't slide smoothly into an unsized neck, this reamer is the solution.
Built from high-grade, wear-resistant tool steel, the Forster reamer features a staggered tooth design that cuts brass cleanly without chatter or tool chatter marks that can weaken case necks. The reaming geometry is ground to .0025" to .003" over maximum bullet diameter, giving you a controlled, snug fit without binding. This precision matters: uniform neck walls reduce bullet runout, improve concentricity, and contribute to tighter shot groups at the range.
Proper timing in your reloading sequence is critical with any neck reamer. Always perform reaming after firing a complete loaded round and before running cases through your neck or full-length sizing die. This ensures the brass has moved to its natural position and hasn't been compressed by sizing yet. If you're serious about case prep and want to eliminate the variables that come with thick, inconsistent case necks, a quality inside neck reamer belongs in your bench.

Frequently Asked Questions
When should I use an inside neck reamer in my reloading workflow?
Use this reamer after firing a complete loaded round and before neck sizing or full-length sizing operations. Reaming is your first case prep step once you've fired brass and want to manage neck wall thickness.
How do I know if my cases need inside neck reaming?
Take a fired, unsized case and try to slide a bullet into the neck by hand. If you feel interference or resistance, excess brass is built up on the inside of the neck and reaming will help. You can also measure wall thickness with a tubing micrometer if you want precise numbers.
What's the difference between inside neck reaming and outside neck turning?
Inside neck reaming removes excess brass from the interior of the case neck using a cutting tool. Outside neck turning removes material from the outer surface. Many precision handloaders do both to achieve consistent, uniform neck dimensions, but reaming alone addresses interior buildup.
Is this reamer compatible with my specific caliber?
This reamer is sized at 0.2265", which corresponds to specific rifle calibers. Verify your cartridge's correct neck diameter before ordering to ensure proper fit and function.
