Lee's Factory Crimp Die for 7.62x39 delivers precision crimping that improves accuracy by building higher start pressure for more uniform velocity. Works with all bullet types.
The Lee Factory Crimp Die represents a significant advancement in ammunition reloading precision. This specialized tool crimps bullets more firmly than conventional methods, resulting in measurable improvements in accuracy and consistency.
A firm crimp forces the pressure curve to build to a higher level before the bullet begins to move. This higher start pressure ensures a more uniform pressure curve and less velocity variation from round to round—the hallmark of quality ammunition.
Testing demonstrates that even bullets with no crimp groove shoot more accurately when properly crimped. The improved pressure consistency translates directly to tighter groups and more predictable ballistics downrange.
Whether you're loading for precision rifle work or general shooting, the Lee Factory Crimp Die delivers the kind of ammunition quality that separates careful reloaders from casual ones.
