Fifty five grains of IMR/AA or H4350 with a 168 or 175 is an excellent target load in a 30-06 bolt gun. I have shot ammunition cans of the stuff out to 600 yards and shot HM scores with that load. The differences between brands of 4350 is slight, if you were developing a maximum load then you would have to pay attention to the lot to lot differences, but at this load level, pushing a bullet just at 2700 fps, that is probably below 50,000 psia with every brand of 4350.

For future reference, if you ever plan to shoot this in a Garand, this powder is not appropriate for use in a Garand. Port pressures would be too high. IMR 3031 has an appropriate curve for a gas gun it will also shoot very well in the 30-06 with a 168.
