Just a quick question is anyone using a Hydro die ?
I want to form some 6MM dasher brass and the Hydro die seems to be the way to go.
Anything I should be aware off ?

Re: Hydro Forming Dies
I used one to improve 338 Lapua brass,
The trick with a hydro die is you have to improve the case more
than you need and the size back down.
The 338 Lap case neck was only going 6.5mm in the die, hydro then resize.
I tried 6mm but it wrinkled the shoulder when I resized them.
It worked well.
You won't get a perfect sharp shoulder but you can run fullish loads from the start.
Not to hot or your brass won't last long.

Re: Hydro Forming Dies
Or you could just load up with trail boss and cheap, pulled or no other use bullets. Trail boss fireforming is relatively quiet and doesn't heat the barrel up, so throat erosion not an issue.
