Lee Factory Crimp Die, 8.6 Blackout

The Lee Factory Crimp Die for 8.6 Blackout (Lee part no. 91924) applies a firmer crimp than most other crimping methods, holding the bullet securely enough that even bullets without a crimp groove can show improved accuracy. A firm crimp raises the pressure needed to start the bullet moving down the bore, and that higher starting pressure produces a more uniform pressure curve and less shot-to-shot velocity variation, both of which translate directly into tighter groups.
