Anyone with the Redding form and trim dies, do you need both form and form & trim die, or do you just need the form & trim die to make 221 out of 223? Also looking for dies to make 221 out of 223.
 
It isn’t a one step process. I suppose you could skip step one but you would probably get a lot of creased cases. The picture shows the steps for the 2 dies. This just gets you to the point of being ready for the full length sizing and final trim to length.

Could you trim the 223 brass prior to the first forming step to reduce the amount of brass you have to shove through that die or do you need the necked down portion to start?
I know you would still have to trim to final length after.
 
There are a lot of ways to skin this cat. I don’t know if one way is better than another and someone’s set up and personal preference on the order will decide what’s best if that makes sense.

What I have ended up doing is the initial 2 sizing steps and trim with a harbor freight chop saw leaving them long. Final trimming is done after the final full length sizing. I also anneal after the first forming step. You know where the new shoulder will be at this point and it helps give a good pass through the final sizing step. On my last pass through the full length die I also leave the case in the die for a good 3 seconds or so and that has helped eliminate any brass spring back.
