L.E. Wilson 6Mm (0.2455''-0.246'') Inside Neck Reamer
$40.48
The L.E. Wilson 6mm Inside Neck Reamer (0.2455″–0.246″) is a precision case preparation tool for handloaders who demand accuracy and consistency from their ammunition. After multiple sizing and firing cycles, case necks accumulate material buildup that can lead to high chamber pressures and unpredictable shot groups. This reamer removes that buildup, restoring your brass to spec and helping you maintain tight velocity spreads and predictable ballistics downrange.
Wilson inside neck reamers are designed to work on as-fired brass—no need to size cases first. The tool is particularly useful when you're working with thick-necked brass or wildcats formed from parent cases, where neck consistency becomes critical to reliable, safe shooting. Whether you're preparing match-grade ammunition for the range or hunting loads that demand repeatability, having properly reamed necks is a fundamental step in the reloading process that's often overlooked but pays real dividends in performance.
This reamer comes complete with a knob-style handle, giving you the leverage and control needed for smooth, even cutting. It's manufactured in the U.S.A., reflecting the same domestic quality and attention to detail you'd expect from a tool maker who understands the reloader's craft. If you need custom sizing outside the standard range, L.E. Wilson can grind special sizes to order.

Frequently Asked Questions
Do I need to size my brass before using an inside neck reamer?
No. L.E. Wilson inside neck reamers are sized for use on as-fired, un-sized cases. This design lets you remove neck buildup without an extra sizing step.
What problem does an inside neck reamer solve?
Material buildup in case necks—caused by repeated firing and sizing—can create tight, inconsistent neck tension and raise chamber pressures unexpectedly. Reaming restores neck walls to consistent thickness and diameter, improving pressure control and shot-to-shot velocity consistency.
Can I use this reamer for wildcat cartridges?
Yes. The reamer is suitable for reaming necks on cases formed from parent cases, as long as the neck diameter falls within the 0.2455″–0.246″ range specified for 6mm.
What's included in this purchase?
The package includes one inside neck reamer and one knob-style handle for operation.
