L.E. Wilson 30 Caliber (0.311''-0.3115'') Inside Neck Reamer
$40.48
The L.E. Wilson 30 Caliber Inside Neck Reamer (0.311″–0.3115″) is a precision case-prep tool designed for reloaders who fire their brass multiple times and need to manage neck buildup. After repeated sizing cycles, case necks can thicken and harden, trapping bullets in the chamber and spiking pressure to unsafe levels. This inside neck reamer cuts away that material cleanly, restoring proper neck dimensions and consistency shot to shot.
Built in the USA, this 30-caliber reamer comes ready to use with a knob-style handle—no separate purchase needed. The tool is sized to work on as-fired brass without pre-sizing, making it straightforward to integrate into your case-prep workflow. Reloaders also use inside neck reamers when forming wildcats from parent brass, though this tool is primarily engineered for maintenance of standard 30-caliber rifle brass.
Quality neck reaming takes just seconds per case and pays dividends in accuracy and safety. If you're stretching brass life and keeping a tight reload routine, an inside neck reamer is the difference between erratic groups and reliable, repeatable performance at the range or in the field. L.E. Wilson is known for precision tooling that holds tight tolerances—exactly what matters when you're managing case dimensions to a few thousandths of an inch.

Frequently Asked Questions
When do I need an inside neck reamer?
After multiple firing cycles, case necks thicken from work-hardening and buildup. If your rounds feel tight in the chamber or you're seeing pressure signs and erratic accuracy, your necks likely need reaming. This tool removes that excess material before resizing, restoring consistent neck thickness.
Can I use this reamer on sized brass?
No—this tool is designed for use on as-fired, unsized brass. The reamer diameter is sized accordingly for that application.
Is the handle included?
Yes. The price includes one knob-style handle and the reamer itself, so you're ready to start prepping cases out of the box.
Can I use this for wildcat cartridges?
Inside neck reamers can be used when forming wildcats from parent brass, though this particular tool is engineered for standard 30-caliber applications. Contact L.E. Wilson directly if you have a specialized wildcat requirement.
