Thread: >20 Practical Bushing Size

I'm in the process of building a .20 practical upper. Can those who already shoot this round advise what bushing size to use for
forming using a Redding F/L S type sizing die? I'm using mainly ADI and Starline brass.

I've read various options suggesting .226 or .228 but would like some real world info.

Looking to not neck turn with 32gr or 40 gr v-max pills.

Thanks for any help you can offer.
