I tried searching the forum on the subject and drew a blank. How do you blokes measure case volume?

Is there any prefered method other than making a deduction based on the weight of the case?

Thanks in advance.

G'Day Alastair,
my understanding of measuring case volume is a once fired case with a dead primer still in it, is weighed, and then filled with water and weighed again. The difference is the volume of the case measured as the weight of water it holds.

hope this helps

+1 Weigh the empty case with a dead primer installed, put water in the case to be level with the top edge of the brass and weigh the case. Subtract the empty weight from the filled with water weight and that is the grain of water that eh case holds.

I think you are supposed to add just a little alcohol to the water so it releases the surface tension. Be consistant on that because the density of the water is different then.
 
Thank you Gentlemen.

BTW is there a tollerance you use once you have determined the case volume?
