LRRPF52 has stated many times that a tight twist will help keep the bullet more stable I.E well behaved as it transitions from supersonic to transonic.
After shooting 1000 yards with both at and bolt action grendels with 8 twist barrels and then getting to try it with my 16 inch ar grendel with the 7.5 twist.
I'm of the mind set that I don't want 8 twist barrels any more.
And from now on 7.5 or 7 twist is where I want to be at.
Buenos side effect is with the tighter twist rate you rpm on your bullet goes up and that directly translates too bullet performance on game.
Is it measurable difference? Sure not by eye I'm sure. But my gut tells me a bullet that's spinning at 300,000 rpm is going to do more damage to a animal then a bullet spinning at 200,000 rpm.
Hope this helps OP.
