OP, The .300WM w/ a 200gr Partition is great out to 600 yards. 650 is stretching its' limits as far as the energy it carries. As stated, even 400 yards is a long shot for most folks. For an ethical kill on Elk, 1500fpe is considered the bottom of the scale. At 650 yards the bullet carries about 1442fpe w/ a MV of 2950fps which is average for the bullet weight.
Freedom is not free. The best of us always leave too soon.
