Best twist rate for a bolt action Grendel

[Joseph5]

Todd Hodnet who does a lot of training of military snipers and also rifle/load/ammunition testing and development for the military wrote an article discussing twist rates and bullet stability. One barrel he mentioned testing was either a 1 in 4 or 1 in 6 twist 308 chambered barrel. He stated that he found lots of advantages to shooting a faster than traditional twist and no downsides.
