80% of the time best accuracy comes at the max load
I don't agree with that one bit, to the contrary, I find the opposite to be true.
308: The Army discovered a long time ago that 2200 FPS seems to be the most accurate. My 40 years of shooting High Power with the 308 bears that out. Although I jumped up to about 2250 because it works the action of the M14/M1A.

2200 fps MIGHT be the most accurate load, but if I only wanted 2200 fps I'll buy a 30-30 instead of a 308. There are more important things than shrinking goups by an extra .001". I expect my bullets to shoot flat over extended distances and hit with a little power out to 300-400 yards.
I've also found my best accuracy right at, or just under max loads. If that doesn't happen with powder "A", then I change to another powder until I get the results I want.
These are the results I get with a max load of Varget and 150's from a 308. About 650 fps faster than the military load. I've gotten similar results from all of the chamberings I load for.
