I'm seriously considering a .300 blackout for my next AR build, especially since MI may be getting suppressors soon. Anyways, not sure what twist I should go with as I plan on shooting both sub and supersonic loads through it...found plenty as to which is best for each, but not so much for what works for shooting everything.

Will I find that I'm unable to shoot both types of ammo without accuracy issues, or is there a sweet spot that lets me run both types of ammo with good results?

Sorry if this has been discussed before, searching didn't get me far both here and elsewhere on the interwebz.
