Blair look along the top row, there is a feature called OBT which stands for Optimal Barrel Time.
In THEORY this gives accuracy nodes based on the harmonics of the barrel length.
Dont know how true...

mawzer308 Just did it on Gordons reloading tool and got 2944fps with 60474 PSI pressure.
It also tells me that if you use 58.95 grains it will give you an accuracy node.
