The LEE Long Charging Die is for use with the Auto-Disk, Pro Auto-Disk and Auto-Drum Powder Measure. Works with cases 1.760 to 2.620 inches long (223 Rem to 300 Win Mag).
Works the same as the pistol powder through expanding die, except it doesn`t expand the case mouth. Rifle case expansion is done in the sizing die.
For cases .860 to 1.760 inches long, use the short charging die.
