I agree with JAsmith. At Grendel speeds, I don’t think you’ll over twist the pills in a 7 twist, though you may lose some velocity and experience some pressure sooner with the heavy pills. All of this is complete speculation. If possible I think I would go with the 7.5 as bill alexander has already done the legwork and established some parameters to follow on the 16” and shorter barrels
