Reloaders who stretch their brass through multiple firings know that case necks can thicken over time, and that extra material can crowd the chamber and throw your pressures and accuracy out of whack. The L.E. Wilson 22 Caliber Inside Neck Reamer is built to deal with exactly that problem. Ground from hardened steel with a finish diameter of 0.2265" to 0.227", this reamer shaves excess brass from inside the neck so there's proper clearance between your case and the chamber.
One of the nice things about the Wilson system is how it all works together. This reamer isn't a standalone gadget; it drops into your Wilson Case Trimmer right where the regular cutter goes, turning your trimmer into a neck reaming station in a couple of minutes. You load a fired, unsized case into the matching Wilson case holder, seat it firmly so it won't spin, then run the reamer in to cut the inside of the neck clean and even. Keep in mind you'll want the Wilson Case Trimmer and the proper case holder on hand, since those aren't part of this package.
This tool really shines in two situations. First, on brass that's been loaded several times and built up material in the neck, it resets things back toward factory wall thickness and helps even out neck tension, which bottleneck shooters chasing tighter groups tend to appreciate. Second, it's a go-to when you're forming wildcat cases from a parent case, since necking brass down often leaves you with thicker walls that need to come back into spec. It's also a solid way to knock out the donut that can form at the base of the neck after repeated sizing.
Worth noting: this is a reamer, not a uniformer. It removes material evenly from the neck walls rather than truing up every case to a benchrest-level match, so pair it with good brass prep habits. Like the rest of the Wilson line, it's made in the USA by a family-run shop that's been turning out reloading tools since 1927.
It removes excess brass from the inside of your .22 caliber case necks so there's proper clearance between the neck and the chamber. Thick necks can drive up chamber pressure and hurt accuracy, and this reamer trims them back toward factory wall thickness. It also helps even out neck tension across your brass.
You'll need the L.E. Wilson Case Trimmer and the matching case holder to run it. The reamer replaces the standard trimmer cutter, turning your trimmer into a neck reaming setup. Those pieces are sold separately and aren't included with this reamer.
Yes. Standard Wilson reamers like the INR-220 are sized for use on fired, unsized cases. Seat the case firmly in the holder so it doesn't spin while you ream, and you'll get a clean, even cut.
You can. Necking a parent case down to .22 caliber often leaves the neck walls too thick, and this reamer brings them back into spec. It's also handy for clearing out the donut that can build up at the base of the neck after repeated sizing.
