Maximum shots allowed to harvest a big game animal

Just wanted to know how many times a licensed hunter can fire at a bull elk before it becomes "Unsportsmanlike" per say and becomes illegal? And can I dispatch an animal with a side arm if said big game animal is badly and or fatally wounded with a bow?
There is no maximum number of shots that can be fired at an elk in Idaho.  During an archery-only season, you may not use any type of firearm for dispatching an animal.
