We had a married couple get an elk a piece this year in our area. They are both in their early nineties. Her a cow as I recall and his a big 6pt bull. They got them out whole by themselves, well with the help of their tractor. I don't know what calibers they were using, but it was on their ranch, a ranch the elk winter on I believe. So, they could probably get away without shooting at a bad angle. Plus they live on the ground the elk frequent.
