Maximum case capacity

[TedB]

My reloading manuals are away, far away at the moment. What is the maximum case capacity for:

6.5X55 Swede
6.5X284

I don't care what powder, just the same for both. I am looking at the relation between the two cartridges. Thanks in advance.

Swede: 52 gr. H2O
Norma: 68 " "

My measure is swede 57.3 water and 6.5-284 is 65.5gr water.

I've been curious about the 1-2 gr volume difference between different manufactures of brass in .308, but this is a bit larger - which brass are each of you using? And the meniscus - is it near flat?
