Has any body tried this yet. I want to shoot the 90 grainers and am thinking of making 'em really haul ass.
 
Re: 223 WSSM 6.5 twist?

Somewhat related to your post.

I tried 6mm 105 Berger VLD's from 3150 to 3312 fps to see how they'd shoot.Accuracy severely dropped off around 3200 fps.This was out of a 7 twist barrel though.

Also from what I've read certain bullets shoot best at a specific velocity range.
