I keep thinking back to whar Ryan Rothhaar said."You really realize how big they are when they are on the ground."
It's truly an understatement.It is an eye opener to stand over the first one.Big creatures and tough.
My thoughts are,if you have to go in the low 50's,make sure it is an efficient setup,especially the arrow an broadhead.The broadhead and shaft need to be tough and tuned,and of a weight you know will penetrate well.
If anything is ever going to go wrong in the field,being within bow range of a screaming bull after days of playing tag and possibly after extreme physical exertion,would probably be the place.The more you can handle well,the better.
Many people travel and incur a lot of expense to go on an elk hunt so a good bit is at stake.So many things can go wrong at the moment of truth but equipment failure should be the last on that list.There are months before an elk hunt to work into or work up a good elk setup.
