Personally if I was to bother neck turning and having to have a custom chamber reamer made to suit the new neck dia, Id be looking at making it .20cal and 40deg improved at the same time. That would be the perfect calibre in this little hot rod, the same weight bullets only faster with a higher BC.

This would be a very cool round as a 20 Cal. Not sure I'd go with a 40 degree shoulder just for feeding considerations, maybe 30 degrees and shorten 20 Tactical dies? I have thought about doing a 20 Vartarg but this could be a better option. I have a 20 Tactical reamer and a barrel on the way for it
