Look for something that features a 180 grain bullet. I doubt if you can find any 300 WM rounds, from any manufacturer, with 180 grain bullets that will not take an elk cleanly. The premium bullets will dig a little deeper, but you truly do not need them if you have enough bullet weight. The Nosler Partition or Accubond bullets are excellent. If you need to shoot copper a bullet weight of roughly 165 works well in a 300 WM.
