From what I've read, it varies considerably from case brand to case brand and chamber to chamber....so if you have a 400 Whelen, can you measure the case capacity in grains of H2O, measured to the top of the case mouth and also tell me the case brand.
Thanks in advance...sorry for any inconvenience...
