I just saw another you tube video of a professional bow hunter taking a 109 yd shot a elk with an expandable so they must be very good. expandables are super quiet and elk don't move forward when you use expandable heads and wind and branches have zero effectWhen they legalize them they’ll be in my quiver for deer and bear just like they’re are in all of the out of state places I hunt. You can’t beat the blood trails a grim reaper leaves and they give a little more for error in shot execution compared to a fix. I’ll continue to shoot a fix blade for elk like I always do. Simply for me it comes down to freedom of choice. They are another lethal option and we should be allowed to make that decision ourselves.
