I'm not sure where you get the notion that you have to measure case volume perfectly.
Not once have I done so. There is a lot of data built into the program, much of which is generic but
which you can edit, if you so desired. Really no need to.
All that is required is for you to select cartridge, projectile, propellant type, and charge weight. The calculated result will show a chamber pressure curve, whether or not that curve is within or beyond SAAMI spec's, and a lot of other useful data such as velocity, energy etc.
I think you have rejected a very useful tool long before you've actually seen it in use.
