Question about .20 Practical.
This information takes differing approaches to neck sizing. #1 is one pass w/ .230........# 2 is two passes w/ 225. and 233.

"The brass formed as easily as expected. I just used a Redding type ”S” bushing die with a .230 bushing and with just one step I had a 20 caliber case ready to shoot."
and http://www.6mmbr.com/gunweek090.html
"To prepare the brass, all you need is a .223 Rem bushing die with .233" and .225" bushings, ........ Put the .233" bushing in a Redding Type 'S' bushing die and run your cases through for a first pass. Then swap in the smaller .225" bushing for the second pass. Now your brass is sized and ready for loading."
Any .20 Practical users have comments concerning superiority of a single pass or several?

Re: Question about .20 Practical.
I'd recommend the 2 step process. Instead of an expensive bushing die, look at some of the cheap full body 223 dies, friend had a Hdy that put the necks at .237", good enough for the .224-.228 second step and preferred preload. 10-12 thou a step should work fine. Neck thickness will vary quite a bit from brand to brand, final will depend on your brass brand. If you choose range brass or surp, probably want to separate brands.
