I was able to get 2830 with VV N560 in my 28" barreled CM, but it was just this side of pressure. Also when compared to other high BC bullets in the 140 range and the 135 ATip, the juice was not worth he squeeze. The performance of the other bullets was actually better when you pushed them at or just above 2900. I can get there with RL 16 somewhere in the low to mid 42 grain area. The 153s required over 44 of N560. Dope at a mile was around 2 MOA more with the 153 at 2830 vs the 135 or 142 around 2900. Easier on components and barrel. To each their own.
