A gusher eh?
When I see comments like this, I sigh.
I've seen gushers from a low shots with a 2 blade....and I've seen almost nothing from a high shot with a big mechanical....and everything in between.
I've seen hundreds of animals shot with an arrow and the one consistent fact; High shots don't leave a bunch on blood on the ground while low shots do. The BH matter much less than the shot location as high shots put a lot of the blood draining into the animal.
Then there is the fact that a pass through shot to the lungs is one of the fastest ways to put an animal down...nevermind, lets focus on draining their blood on the ground. grin.
I don't know when Bowhunters mentality changed from killing animals quickly to putting blood on the ground. Probably the Rage advertising, "Throw an axe at them."
My buddy tells a story of an elk he shot that was leaving a great blood trail. They tracked that blood thinking he will be down just around the corner....for over 2 miles. They came on the bull that had been shot again by another bowhunter....his kill. Every time someone says blood is their #1 factor in their BH decision I think of that story.
