Lee Factory Crimp Die for 5.7x28 FN
Lee's Factory Crimp Die uses a collet to apply a rifle-style crimp to 5.7x28 FN cartridges. A firm crimp improves accuracy by ensuring consistent pressure buildup and reduced velocity variation.
Lee Factory Crimp Die for 5.7x28 FN
Reloading the 5.7x28 FN presents unique challenges, particularly when it comes to crimping. Lee's Factory Crimp Die solves this problem with a collet-based design that applies a powerful rifle-style crimp to even the most difficult bottleneck cases.
Key Features
- Collet-based crimping system applies consistent, powerful crimp pressure
- Works with or without crimp grooves — the collet is powerful enough to form its own groove
- Improves accuracy by ensuring bullets remain firmly seated during firing
- Reduces velocity variation through more uniform pressure curves
- Designed specifically for 5.7x28 FN bottleneck cartridges
Why Crimp Matters
A firm crimp ensures that bullet movement is minimized during the pressure buildup phase of firing. This consistency translates directly to tighter velocity spreads and improved downrange accuracy. Even bullets without traditional crimp grooves will benefit from the collet's gripping action.
The Bottom Line
If you're serious about reloading 5.7x28 FN ammunition, the Lee Factory Crimp Die removes one of the caliber's most frustrating obstacles. It's a straightforward, effective solution that delivers measurable improvements in ammunition consistency and performance.
