RCBS 9327 Case Neck Brush Small .22-.25 Cal Nylon Cleaning Tool

The RCBS 9327 Case Neck Brush in Small size is a dedicated cleaning tool for reloaders working with .22- to .25-caliber cartridge cases. If you're prepping brass for handloading, fired cases accumulate powder residue, dirt, and carbon deposits inside the neck—exactly where precision matters most. This nylon brush reaches into the case neck and down the interior walls to scrub away buildup that can affect bullet seating and overall ammunition consistency. It's a simple, inexpensive step in your case preparation routine that pays dividends in load quality.

RCBS makes separate sizes to match different caliber families, so you're not forcing a oversized brush into delicate .22 cases or undersizing a tool meant for magnum rounds. The Small version threads or attaches to your case cleaning setup (whether you're running it by hand or through a tumbler), and the nylon bristles are effective without being so aggressive they damage case necks. Anyone serious about reloading precision knows that clean brass is the foundation—this brush takes that task from tedious to straightforward.

The RCBS Case Neck Brush is a workhorse accessory that belongs in every reloader's prep kit, especially if you're loading smaller calibers. Pair it with your existing case cleaning process, and you'll notice cleaner necks, better bullet fit, and more uniform loads downrange.
