Let’s Dive into Lee 90066 Factory Crimp Die 30/284
The Lee 90066 Factory Crimp Die 30/284 is a single-stage reloading die designed to improve the accuracy and consistency of ammunition. This die, manufactured by Lee, is specifically chambered for the .224 Valkyrie cartridge, though it handles .30 caliber projectiles, making it versatile. It stands out due to its ability to apply a collet-style crimp, ensuring a uniform and firm hold on the bullet.
My journey to discovering the Lee 90066 Factory Crimp Die 30/284 began with a frustrating issue: inconsistent bullet seating depth and neck tension in my .224 Valkyrie reloads. I was chasing that sub-MOA accuracy, and the factory crimp die promised to be the missing link. I was aiming for the consistency needed to produce accurate, repeatable rounds for long-range target shooting.
Unboxing the Lee 90066 Factory Crimp Die 30/284 revealed a robust-looking piece of steel, finished with Lee’s characteristic black oxide. It felt solid and well-made, a reassuring sign. The die came with clear instructions and the necessary adjusting wrench.
Compared to other crimping methods, like roll crimps or taper crimps which I have used on pistol rounds, the Lee Factory Crimp Die stood out for its collet design. This design appeared to offer a more uniform and controlled crimp. I chose this die over a Redding or Forster die primarily for its positive crimp action and Lee’s reputation for value.
My first impression was cautiously optimistic. While it looked well-made, the proof would be in the performance. I was excited to see if it could actually deliver the accuracy and consistency improvements I was hoping for.

I initially tested the Lee 90066 Factory Crimp Die 30/284 at my local shooting range, working up loads for my AR-15 chambered in .224 Valkyrie. I prepared a batch of test rounds with varying powder charges and bullet seating depths, then applied the factory crimp. The crimping process was smooth and straightforward, requiring minimal adjustment.
The die performed exceptionally well under controlled conditions, and the crimp seemed unaffected by slight variations in case length or bullet seating depth. It was easy to use, even for a reloading novice. The Lee 90066 Factory Crimp Die 30/284 didn’t have any issues with setup, and I noticed more consistent bullet seating depths.
