260rem H2o Capacity?

[poison123]

What are you guys getting for your self measure H2o capacity? I've got some necked down 7mm-08 brass and got the following data on them.


Case Case+Primer+water
162.7 221.7 = 59
162.5 221.1 = 58.6
162.9 221.6 = 58.7
164.5 223.1 = 58.6
163.9 222.7 = 58.8

So 58.7 is the average with QL saying 53.5

I'm curious what people are seeing.

And I'm working on building a new 139gr Scenar load.
