I suggest that you ask your question at this website: http://forums.accuratereloading.com/eve/forums/a/frm/f/760101804 in lieu of Nitro Express as this website has much more activity. Someone in response to your question is likely to give you some historical data about the .470NE development due to the British ban on .450 calibers in some of the colonies. Is your .450 the .450 NE or the .450 #2 NE?
