I'm using the 180g Nosler BT in my 15" 338WM. It zips out at 2840fps. I've only taken one deer so far with it but it performed admirably. That was a small buck at 25-30yds. The exit hole was golf ball sized. Hopefully I'll add a few more this season. I've also taken several deer using the 200g Hornady Sp. They also worked quite well. Good luck on whichever way you go and do keep us informed.
