One thing that started this was determining the effect of bullet weight on performance. FWIW, bullet weight has little bearing on external ballistics, but, it does affect the muzzle velocity as the force it takes to accelerate the bullet differs. The consistency can be an issue if the bullet is 'lopsided' due to the difference in weight.
Sorry I misread your post so am revising this part.
The .338 data kinda surprised me. Combined with the data on powder measures and resultant velocity it seems that we might be better off with charges measured by volume instead of weight.
I was a test engineer on high power laser systems for many years so this kind of stuff is what I live for :) More data is always better.
