The Lee Precision 90585 powder thru expanding die for .45 ACP streamlines the reloading process by handling two critical steps in a single station. This die charges your cases with powder while simultaneously expanding the case mouth, reducing the number of operations needed at your progressive press. It's built for serious reloaders who want efficiency without sacrificing consistency—whether you're working with .45 ACP, .45 Auto Rim, or .45 Win Mag cartridges.
This is where Lee's straightforward engineering philosophy shines. Rather than fussing with separate expanding and charging operations, you get both done in one stroke. Pair it with a powder funnel adapter, or run it with Lee's Auto Disk or Pro Auto Disk powder measure for automated charging. It integrates cleanly into most progressive reloading setups, letting you focus on volume without corners cut on precision.
Lee Precision has built a reputation on making reloading accessible without cutting quality. The 90585 is no exception—it's a workhorse die that handles the backbone work of case prep so you can spend your time perfecting load development and quality control. If you're building match ammunition or just cranking out reliable defensive rounds, this die pulls its weight on the bench.
