Is there a simple yet accurate way of measuring a case's usefull capacity?
I think that this is important since accuracy depends on consistency and since there may be variations in cases of the same make and even of the same lot, it would be helpfull to know how consistent your brass is.
Also, I heard that one should not use commercial reloading data intended for use in commercial brass when reloading military surplus brass or cases with thicker than usual walls beacuse of the diminished capacity of these which could lead to a dangerous increment in pressure, so finding out if the brass you will use is within normal commercial specs is also good for safety.
I have read that you could weigh your cases and if they have different weights, but equall outside dimensions, then the heavier case would probably have thicker walls an consequently smaller capacity.
But what about filling cases with liquid and measuring the amount with a syringe? Could this work as well, and perhaps be more reliable? Are there other ways or is this just not critical enough to bother?
