To size down to 221 Fireball I use the Redding form die 90101 then use the 83101 form and trim die. They are then annealed then switched over to the CH4D 17 Mach IV form dies I have. Then cleaned and annealed. Full length re sized and expanded, trim to length and neck-turned. Primer pockets uniformed and deburred. Fire formed using 25gr HP. After fireformed ,cleaning and resizing the case. they then have a shallow expanding of the neck and re neck-turned as a clean up and to remove the donuts. I have more success using H4198 ( AR 2207 ) with the 20gr V-Max but use Benchmark with the 25gr V-Max
