RE: broadheads for elk???
Another vote for COC heads, since most are shooting 100gr bh's now a days! I am using 100gr Steelforce Premiums as well, they have performedflawlessly and group the best of any BH'd out of my current bow. A very close second was the Magnus Stingers.
I can't say anything bad about Muzzy or Thunderhead 125 gr fixed Bh's though, both have worked to harvest black bear, elk and moose in the past out my bows.
