Gentlemen,
I have made .17 Fireball brass from .223 and .222 brass, I have the forming dies and it's no big deal. I have made .32-40 brass from .30-30 and .32 spl from .30-30 and even .38-55 from .30-30.
Now I am diving into a pool of which I have no experience. I have some .32-20 brass (new) and wish to make it into .25-20 brass. Do I just run it through a .25-20 sizing die? Usually I anneal my formed brass after they are formed, should I anneal these before?
THank you in advance for your input.
