You cannot misinterpret or mangle physics or empirical data enough to convince me that shape does not matter. It does.
---But then I must be biased due to falling for the 284 Win and 300WSM cases the moment I touched them off---before even trying to compare their shape vs performance.
I also bet that those brainiacs that are custom blending powder for the short, fats are taking after those infernal fishing lure people. Just out to catch the fisherman (by the wallet) not actually catch more and bigger fish.

The merits (or lack of) shape have been hammered here before.

There are very few instances in this world where shape does not matter--I am trying to think of one now but...
