The Forster Products 0.2865'' Inside Neck Reamer is a precision case-preparation tool built for serious reloaders who want consistent neck wall thickness across their ammunition. If you're turning out match-grade or precision hunting loads, neck reaming removes excess brass from the interior of case necks—a critical step that many reloaders overlook but that directly affects bullet seating consistency and overall load uniformity.
Forster's Inside Neck Reamer is manufactured from high-grade, wear-resistant tool steel and is ground to a diameter 0.0025'' to 0.003'' over maximum bullet diameter. The staggered tooth design cuts smoothly without chatter, producing clean reaming action that won't damage case necks. The 0.2865'' size matches cases like 7mm cartridges and similar applications—verify your specific cartridge dimension before ordering.
Proper neck reaming technique matters: perform reaming after firing with a full load and before neck or full-length sizing. A quick way to check if your cases need reaming is simple—try sliding a bullet into a fired, unsized case neck. If you feel binding or resistance, excess brass is present and reaming will improve consistency. For precise measurement, a tubing micrometer lets you monitor wall thickness as you work.
Whether you're chasing sub-MOA groups on the range or preparing premium hunting ammunition, this reamer is built to last and deliver the precision that separates hand-loaded ammo from factory rounds.

Frequently Asked Questions
What cartridges use the 0.2865'' neck reamer?
The 0.2865'' diameter fits cartridges with neck diameters in that range, including 7mm calibers and similar applications. Confirm your specific cartridge neck diameter before ordering to ensure compatibility.
When should I ream case necks during the reloading process?
Neck reaming should be performed after firing cases with a full load and before neck or full-length sizing operations. This sequence ensures you're working with fireformed brass and preparing it for the next loading cycle.
How do I know if my cases actually need reaming?
A simple field test: try sliding a bullet into a fired, unsized case neck. If you feel interference or binding, excess brass is present and reaming will improve consistency. For more precise measurement, use a tubing micrometer to check wall thickness.
Why does reaming matter for ammunition quality?
Uniform neck wall thickness ensures consistent bullet seating pressure and runout, which directly improves accuracy and load uniformity—especially important for precision hunting or range ammunition.
