LEE 5.7×28 Steel 2-Die Set

The Lee 5.7×28 Steel 2-Die Set includes Full Length Sizing Die Bullet Seating Die Universal Shell Holder powder dipper and Instructions/Load data.

If you wish to utilize a Lee Pro Auto-Disk or Auto-Drum Powder Measure with this die set you will need the short charging die LEE90668 (sold separately). Lee resizing lubricant is required with this die set.

It has come to Lee's attention that 5.7 x 28 brass is now potentially fully annealed from case mouth to rim.  This causes many issues with the reloading process. 

Lee's suggestion is to use Lee Resizing Lubricant and a Lee FN Shellholder. The rims are so soft that they cannot be resized with a standard universal shell holder as the brass rims deform and are pushed down into the .260" relief hole that is used for priming.  Lee introduced FN Shell Holder LEE92183 for resizing this brass.  The FN shellholder cannot be used to re-prime brass you will need to use the standard #15 shellholder to do this.  Lee has also seen that the primers are staked or crimped into position.  This maybe due to the brass being so soft that it does not have the ability to hold the primer into position via a slight press fit.

The quick trim die uses a plastic bushing to provide a slight interference fit on the body of the cartridge to hold it stationary while trimming.  This new brass is so soft the plastic bushing is deforming the brass. If this happens to you return your die body to the factory at the address below and we will ream the bushing out to the largest allowable dimension to prevent damage to these soft cases.
