Roger that. I don't know how to compute case capacity. Is there a formula of some sort? It is less than simple volume because you have to account for the webbing at the base. Is there a software program that does this?
Check this out - I was digging through my brass and realized I had some 300 Remington Ultra Magnum brass. This stuff is HUGE! I looked it up, and the exact measurements are .550 at the base, .534" rim, and 2.8" OAL with a .525" shoulder.
Now *THAT* would be a huge powder load for a .450, .44, or .50 sized Intermediates.
