So, yes.

I've read references here to 'having' to buy 'forming dies' to make wildcat cases (or in this case a pistol case from a rifle case). I have done and still do form my cases in the reloading/sizing die. I have never seen the need for a 'forming' die. The hardest wildcat I've had to make, the 38-45 Clerke, still forms quite easily if you use virgin brass and lube it liberally.

(As far as I can tell by looking, 'forming dies' are simply reloading dies with the interior machine operations left out.)
