Lee Precision Factory Crimp Die Features The Lee Precision Factory Crimp Die for .22 ARC is built around a collet that squeezes the case mouth firmly into the crimping groove producing a stronger hold than many conventional crimp dies. Because the collet is powerful enough to form a crimp groove on its own bullets that lack a factory crimp groove can still be crimped effectively widening the range of projectiles a reloader can use. This firm crimp raises the pressure required before the bullet starts to move down the barrel which results in a more consistent pressure curve and less shot-to-shot velocity variation. For reloaders chasing tighter groups at distance that consistency translates directly into more predictable point of impact. This die is sized for the .22 ARC cartridge at a .224 inch bullet diameter and is not a carbide die so reloaders should follow standard lubrication practices during use. It threads into any reloading press using the common 7/8 inch-14 thread pattern making it compatible with the vast majority of single stage and turret presses on the market. A shellholder is not included and must be purchased separately to match the .22 ARC case. For reloaders building precision .22 ARC ammunition this die offers a simple reliable way to add a consistent repeatable crimp to every round.
