if you have the data, could you expand on the case capacity comparisons you showed

338 win mag - xx grn water
340 - xx grn water
330 dakota
338 sin
338 rum
338 edge
338 lapua

I also think this is an interesting prospect as a rechambering of standard 24" 338 win barrels. Sure longer is typically faster, but this should be a similar expansion ratio as 300wsm perhaps, which performs well in 24" tubes.
