My favorite and i mean absolute fav hunting bullet is 162 SST in my 7 mag for deer, SST IMO and i feel like i've tested everything, is the best whitetail bullet, however i wouldn't use it on an elk or bigger game as there are much better options. I took a huge AK moose this year with my 300wm shooting 200gr accubond and it did as good as anything would do. Moose aren't tough they are just big, my advice with a 280 moose hunting would be to shoot a partition, accubond, or a Barnes TTSX. Sure, the 162 SST or ELDX will kill that moose and do a great job IF you stay away from bone. I'd even say theres probably not going to be a better bullet for a double lung shot but you owe it to the animal to use the best bullet per caliber per game for the marginal shot if you get big moose fever! Hope that helps!
