Anyone familiar with this?

Seems there is supporting documentation if you think about it. The Satterlee ladder test.......recall reading where Scott Satterlee said that once he had ID'd the optimal velocity for a gun and bullet, he would get the same results regardless of powder.....as the bullet reached the same velocity.
And one more observation. Doing some research on these ladder tests, I have seen a lot of instances where guys graph their velocities to ID the flat spots. Likely as not, those seem to appear about half to 1 grain short of maximum load data......at a point where case is going to be full of powder....and right o the edge of being a compressed load. A full case load of powder was one of the key conditions the OBTC author had identified as contributing to accuracy.
It all starts pointing in the same direction.
