Case capacity difference?

[Autorotate19]

How do you measure the case capacity difference for 300rum brass between remington and nosler? Also if anyone knows the difference would be awesome.
Thanks

Take a spent brass of each kind with the primer still in it, weight it on your powder scale. Fill it level full of room temperature water and weigh it again on your poweder scale. Subtract the empty case weight from the full case weight. The number you get is the water grain capacity of the brass.

Do that for each type of brass. Compare the water grain capacity of the different case types.
