If you can get them down under, check out the Hornady A-max. I use the 162 in 7mm for deer and antelope with devastating effects. Here's the exit hole in a young antelope my wife shot at 391 yds a few days ago.
I would expect the 140 gr A-max would give similar results. And the .585 BC, compared to .485 for the SST, will help you down range.
There's always the Bergers as well, if your rifle likes them.
