500 yard shot with a .243? either you're not great at range estimating or you're nuts....243 lacks serious energy at that range...not somethign you wnat to try at home..Anyways, I'd go wiht a Remington 700 BDL DM, BDL SS DM, or mountain rifle DM, all in .270 or .30-06. perfect for any deer, anywhere. Detachable Magazines are really handy. I've had mine for 4 years, i've killed 15 deer. no disappoint here.
