Always heard them called "slow elk". Never knew anyone that actually tried to kill one. Although some years a gut pile is found and a few head go missing from local USFS grazing allottments.
A few years ago there was some jackass in a neighboring county driving around gut shooting beeves (22 LR) from the road. The last time I saw it mentioned in the paper, he had killed approximately 8 head. I don't think they ever caught the bastard.
Hopefully a rancher caught him in the act, and that is why we never heard any more about it.
I noticed that was abscessed when the pulled the elk antler out.
Pretty easy fix....
Purge the abscess, flush with water, squirt a 60cc syringe of hydrogen peroxide into the cavity, and give the cow 20cc's of penicillin a day for a couple of days.
