There are several ways to get water volume. First the cartridge must be clean (inside and out) sized and deprimed. Now you need to seat the bullet to your OAL. Then invert bullet down in some holder so you can add water through the primer hole. This will be the exact volume that the powder has to work in. Doing it the easy way base down can give you some false reading since the neck lengths vary slightly.
I've done it all 3 ways. The best is inverted, will give you the best results.
