Does any have the case capacity of 308 win case from nosler in grains of water?
I would like a library of case capacities for all brands of 308 win cases
Case capacity can vary lot to lot even with the same manufacturer.
I have measured a few different 308 cases with water, the numbers that I found may differ from other lots so do not use them as documented for load data.
Winchester. 54.7 - 55.1 grains of water.
Remmington 54.5 - 55.3 "
Lake City 13 53.5 - 53.9 "
It helps when you sort your brass by volume. Everything else would go to establishing an average,
Load data by manufacturers is their specific findings from the equipment and components they used in testing.
Start low and work your loads up with your components.
If and when components are changed you may, perhaps should, work the data again.
Doing a pressure test as part of load development will keep you in a safe zone.

As long as there all measured the same way in comparison it shouldn't matter. I think most are to the top.
One of the reason I ask is if you look at the nosler reloading manual which is also on line they list the case capacity in h2o for there cases with different bullet weights and it didnt make sense.
