7mm RM is perfectly capable as is 7mm-08 and 270 with proper bullet and range.
This^^^^^^^though I don't really prefer a shoulder joint shot, but just behind when possible.
Most good bullets from adequate chamberings will do just fine. Nosler Partitions have never disappointed.

I was hoping you'd chime in as well MM. I think Bob and you both had some 130's recovered from Elk. While I don't target the joint, or front leg bones totally on purpose, if they're on any sorta angle, I do point line up the far leg most times. Just an easy reference point.
