I'm sure this has been beat to death, but here goes. My son and I are going on a 4th season elk hunt in SE Colorado. I will be shooting a 280 Rem. I have 150 grn Nosler Partitions and 139 grn Hornady InterBonds, both work great on Alabama whitetails. But an elk is not an Alabama whitetail. I have accurate loads in the 2900-3000 fps range worked up for both of these. We will limit shots to 200yds, that's my limit with out a good rest. Which do you recommend? Not really trying to start a Dodge vs Chevy debate just need to know.
