In 8 years of hunting elk in western WA, I’ve killed:
Musket - 2 bulls/1 cow
Rifle - 1 bull
The years I didn’t kill one, I either missed, had a misfire, or had my buddy shoot because he only had a couple days of our week long season off. I have a real love/hate relationship with my muzzleloader :/
All of my elk hunting has been in Alaska on Afognak Island. I've shot 11 elk in 18 years. However we hunt as a group and some years I do not even have a tag but I still go along to help and share in the hunt. The other hunters do the same. Over 18 years we have harvested 23 elk (with 3 years where we got shut out). We generally have a week to hunt, and quit once we get one or two elk. I think the average hunt is about 5 days.
