Something else you can try, measure the grains of water from a case fired (but not resized) from your rifle. You have to have it full to the top of the case, tap it to raise any air bubbles and square across the mouth, doing it 2 or 3 times ans averaging the result is best. Send me the result and I'll feed it into Quickload, sometimes that will tell a story (and sometimes not).
Cheers
