Handgun brass that bulges at the base is a common problem for reloaders working with auto-loading pistols—and a standard sizing die can't always reach it. The Lee Bulge Buster Base Sizing Kit solves that problem by removing the low-base bulge that shows up on fired cases in 380 Auto, 40 S&W, and 45 ACP. Unlike conventional dies, this kit uses a push-through design that gets past the shellholder to eliminate bulging, which means more reliable, consistent ammunition every time you reload.
The system is straightforward: the kit includes an extension sleeve, push-through punch, and catch container that work with your Lee Factory Crimp Die (sold separately). Once installed, you simply push bulged cases through the sizing ring—the carbide ring removes the bulge in one operation. It's quick, repeatable, and designed to integrate seamlessly into your existing reloading setup without requiring special equipment or extra steps.
If you're serious about handgun ammunition quality, bulge-free cases matter. They load easier, chamber more reliably, and fire more consistently. This kit is especially valuable if you're processing a lot of range brass or mixing cases from different firearms, where bulging is more likely to occur.
