Sadly the very base is also known as the case head and is cited by some as being a possible safety issue IF you might mistake one for the other Personally, in my opinion, if you are that stupid you should not own a spoon let alone an FAC.
This particular argument is that of someone clutching at straws during an argument they are losing if you ask me.
This said I was taking a mate though reloading .303 at the weekend and he kept forgetting the charge weight (using electronic scales) so I demonstrated just how much powder a .303 case would take. I suspect that for some a powder scale that just needs setting and matching is the way forward.
