See link below. Just my advice (and you can take it or leave it) but "don't re-invent the wheel" here, stick with what works. The web page has just about all the info you need on a 20 Practical.

I use a competion die with a 228 bushing for winchester brass and a 230 for lapua brass.

That's funny, my Winchester brass (and most Lake City I have tried) loads out right around .228" at the neck. You must use almost no neck tension for your loadings. I am working with AR-15's so a bit of neck tension is definitely necessary, especially for magazine feed rounds.

when I measure my cases after sizing the neck measures .227 - .2275. So I am only running between .0005 and .001 neck tension. My rifle is a single shot savage so I do not have to worry about recoil moving the bullet.
