Availability: In Stock
The Lee Precision .427" Diameter Classic Bullet Size Kit is a cast bullet sizing solution built for handloaders who want speed and simplicity. If you're casting your own bullets—whether for .44 Magnum, .45 Colt, or another large-bore cartridge—this kit handles sizing and gas check crimping in one pass through your single-stage press, with no fiddly nose punches or secondary operations required.
The kit works by pushing bullets through nose-first: the sizing die tapers them to proper diameter while simultaneously seating and crimping gas checks in place. Sized bullets drop directly into the included container, keeping your workspace organized and your workflow moving. The standard 7/8x14" threads mount to any single-stage reloading press in place of your normal shell holder, so setup is straightforward if you already have a press on the bench.
This is a complete sizing solution for .427" diameter bullets—one of the most common cast bullet sizes for big-bore revolver and rifle cartridges. To get the most from the kit, you'll want to coat your cast bullets with liquid alox lubricant before sizing (a step that also prepares gas checks for seating). The die is sized .001" larger than typical groove diameter, so bullets size down cleanly without excessive squeeze that can deform them.
Keep in mind: this kit is designed for single-stage presses only. You'll need to provide your own press and bullet lubricant. Lee does not supply top punches for casting molds, but this sizing kit eliminates the need for one—a real advantage if you're hand-casting.
| Bullet Diameter | .427" |
| Press Compatibility | Single-stage press only |
| Thread Size | 7/8x14" |
| What's Included | Sizing die, punch, container |
| Not Included | Reloading press, bullet lubricant |
No—Lee Precision designed this kit specifically for single-stage presses. Progressive and turret presses have different ram and indexing mechanics that aren't compatible with the push-through sizing operation.
Not if you use this sizing kit. The kit's design eliminates the need for a separate top punch, which can simplify your setup if you're hand-casting bullets.
Lee Precision recommends liquid alox. You'll apply it to your cast bullets before running them through the die; the lube also prepares the gas checks for proper seating and crimping.
Select a sizing die that's .001" larger than the groove diameter of your cast bullets. Lee makes Classic Bullet Size Kits in multiple diameters—the .427" is the right choice for .44 Magnum, .45 Colt, and similar large-bore rounds, but verify your bullet diameter before ordering.
