Do I need to anneal? Or just find a die to form them to an intermediate size? Is two steps enough? Can anyone recommend a cheap die to do this?

I form virgins in a Redding FL die,with the seater being an intermediate step. My
Lee's will do likewise,but they [bleep] suck(in all chamberings) and add copious runout.

OneShot and W/W hulls.
