Thanks!
I should also add that the case shape of the .300 does have one advantage: The short, wide powder column results in more consistent pressures and velocities than those of longer .300 magnums. This allows it to be loaded up to slightly higher average pressure, without the highest-velocity individual shots spiking too much above the average. It also tend to result in finer accuracy, but in the average factory rifle this isn't as evident as in custom rifles.
