Forming cases is done simply by running the standard .284 case over a .30 caliber expander button. Just make certain that everything is lubricated nicely. This isn't a big step up, so you shouldn't lose any cases to neck splitting, especially if they are new.

Afterwards, if the rifle has a different shoulder configuration than what is already on the .284's case, fire form to your chamber with 10 to 15 grains of Red Dot powder with the rest of the case filled with cream of wheat, or with a lead bullet (bullets for the .32-20 work nicely) that is seated finger tight.

You can also simply try fire forming the cases without the sizing die, but you might not get very good results.
