Professional-grade inside neck reamer for .22 caliber brass. Removes material buildup from repeated sizing and firing to restore proper neck dimensions, reduce pressure spikes, and improve accuracy.
Serious handloaders know that brass case necks thicken with each firing and sizing cycle. Left unchecked, this buildup creates dangerous pressure spikes and erratic shot-to-shot performance. The Wilson Inside Neck Reamer solves this problem with precision engineering.
Stock reamer sizes are intentionally larger than bullet diameter for use on as-fired brass. This allows you to precisely control neck wall thickness and uniformity—critical factors for consistent velocities and tight shot groups.
If you're loading match ammunition or pushing precision rifle work to its limits, inside neck reaming is essential maintenance. This tool pays for itself in improved accuracy and safer, more consistent loads.
