If you go with a premium bullet such as a partition,failsafe or barnes x a 165gr bullet will penetrate more than enough for elk or moose.If you use a conventional bullet such as a powerpoint or core lokt I would step up to a 180gr.I have killed several elk with 140 gr partitions out of my 7mmstw and all but one bullet exited and that one was a raking shot that travelled through about three feet of elk before stopping under the hide in the neck.
