A lot of people mention moose to justify larger caliber magnums but a 7mm RM worked just fine for me. Although I only have a sample of one it was a one shot, center of chest from the front, drt. The 175 gr Speer Grand Slam cut the liver in half and he dropped in place.
Elk on the other hand seem to be tougher to take without a run with the 7 RM. Never have had a drop right there experience with the 7 Rem Mag. Switched to the .338 Win Mag back in 1999 and that has worked much better. It's 338 caliber minimum now when elk hunting for me.
