Thread: Hornadys new Hydo-form die

Hornady are now making in there custom shop new hydro-dies to form wildcat cases, you just fill the die with water and hit a plunger with a wooden hammer 3-5 times and the case is formed under water pressure into your new wildcat chamber, no more fire forming your cases in your rifle and wearing out your barrel.



Below are some 6mm Dasher cases in different stages of forming in the die, the number of marks on them indicate how many times they have been hit with the wooden hammer.
The case with the smiley face on was and old case work hardened and didn't form well splitting.




To get a hydro-die made by Hornady at there custom shop you must supply them a reamer drawing and 3 formed cases from your wildcat chambering.
Now that this new fire forming die by Hornady is available I might be looking at a few improved chamberings a little more seriously.:grin:

Looking at that would you have bothered to hit it past the 4th whack? - looks like it would have chambered and fireformed from there you reckon?

Cool.... But dumb cos you have to send away fireformed cases and reamer drawings... Ill bet the amount of fucking round to get the damn thing to your dorr ill be fireformed and shooting my hearts content before your order even arrives at hornady

Clever. I like it.

And if you already had a reamer for your wildcat...........why would you not turn and ream your own Hydro Die?

You could, but to get the die to the right size you would have to heat the die body to xxx temp taking into consideration its coeff of expansion to get the right dimensions when it cools and shrinks - more dicking around than its worth?
A die with its guts the same as your chamber (ie off the same reamer and done cold) is a waste of time
