Thanks very much!Not sure if you noticed but this post is from 2006 so you may not get much response from those same posters.
But FWIW, I have a 20-222 and use the Redding Rem 222 competition 3 die set. This exact set here and this is actually a really good price too. https://www.brunoshooters.com/mm5/merchant.mvc?Screen=PROD&Product_Code=4948
Especially for necking brass down I prefer to use a bushing neck size only die so you aren't also FL sizing the brass every time you neck it down.
