If you don't reload, look at some of the loads from Cor-bon in the 240 to 300 gr. range.
As buck460XVR, I reload my own rounds and for deer, the 240 gr. XTP Mags are great. I also loaded up some 260 gr. Nosler Partitions, and some 300 gr. hard cast bullets.
I have shot all of these loads out to 150 and 175 yards, with a scoped S&W 460 Mag. My gun is sighted in for 2 inch's high at 100 yards, with the loads I have, I do not have to hold over at all to hit my 150 and 175 yard targets.
The only sure way to drop them in there tracks is to hit the CNS, brain or spine shot.
I also never like them 200 gr. SST Hornady bullets.
