Here is the really really really really simple answer to your conundrum. Buy this rifle if it is nice, then buy 100+ head stamped 500 3.25” cases but never shoot them. Ask for used .470 brass on this forum and get 100-200 for fun shooting. You will only pay about $1.00 -$2.00 for the .470. Now you will have the .500 cases in the bag for hunting and or re-sale.
