You will need to allow for this.. If my memory serves me correctly I think it’s around 6% Stretch.. The brass will also need to be annealed....400° for an hour should do it...
Thank you...I will add this to my notebook.  I look forward to the challenge.  David...quick question...do you think oiling the rims of the press will help during alleviate stress to the brass?
