Now those that know me would understand... but I missed the first two shots. The bull stepped where I could see just his back end. I thought knock his back legs out from under him. It worked the third shot saw him buckle. We ran down the trail where we could see him, the fourth shot was perfect and he piled up.
Well I might as well be the first to say it. What the heck.
I would have never thought to take out the back end as a first option. 
Can we say wait for a clean shot to make a quick kill.
Was kind of thinking the same thing!!!
