High Accuracy Reloading Press
Designed & Manufactured In Australia
Hydroform dies will save you their initial cost many times over in that you don’t need to fire form the cases. Our dies produce case shoulders that are almost as sharp as fire formed cases, necks without doughnuts and we have found we can process around 100 cases per hour. Saves a lot of powder, primers, projectiles, barrel wear, range time and can be done at any time day or night at your leisure.
These dies are manufactured with a 416 stainless steel body and D2 tool steel drive pins hardened and tempered to prevent scoring in the die. Both pin diameters are precision cylindrically ground after hardening to achieve the smoothest surface possible and accurate dimensions. They also feature a Teflon coated guide bush in the top of the die and an oversized section in the drive pin to help prevent bending of the pin under the head from offline hammer blows. The base is made from 1045 medium carbon steel and Cerakote painted to prevent rusting.

All tolerances are kept to very low limits so that the hydroforming fluid you use (water or thin oil) is not ejected everywhere when you drive the pin home. This also results in very true concentric case necks after hydroforming due to the design of our dies. The drive pin seals the case neck on the inside rather than the shell sealing on the outside against the die, as some other designs use. Our trials carried out over some hundreds of cases in a number of calibres show that we can consistently achieve less than one thousandths of an inch neck runout, whereas neck expanding in a press will often result in .005” or more runout.
Some dies, such as the 6mm PPC and the 30BR Robinett, perform two functions in the one operation by expanding the case neck and blowing the case body out and forward to the required dimension. Other dies like the 6mm BR to 6mm Dasher just move the shoulder forward as required as the parent case is already a 6mm BR case.
If you have a specific calibre or neck diameter you would like to see a hydroform die available for, contact us with the details. Custom chamber dies can be manufactured if you send your chamber reamer to us. Manufacturing time will usually be 4 to 6 weeks maximum and often much less. Case length for head spacing can be customised to suit your rifle chamber and we will need a few empty cases that have been fired in your rifle to do this step. We find we can achieve better results by hydroforming the case a few thousandths shorter than chamber length rather than making it longer and having to compress it back to under chamber length during resizing before loading.
The die thread diameter is the standard .875” x 14tpi 60degree thread form as used on most dies, so it can be used in a standard press if desired. However, we do not supply a blank case holder with a die set, rather we supply a base the die screws into and bottoms out uniformly every time, thus holding case shoulder length constant. All dies are engraved with the part number and calibre size.
