Can't beleive nobody mentioned it but maybe I'm just a chitty shot.
After being shot and bleeding but able to run off, I made the "mistake" of a life time on the biggest bull I'd ever tried to kill. I did NOT give the critter time to bed and stiffen up or bleed out. I gave him about 10 minutes and that 3 legged bull kicked my ass. I jumped him from the creek bottom where he laid down only about 300yds from where he was shot. Had I waited 45 min to an hour I'd have killed him in that bed or he quite possibly he'd have died all by himself.
Had I had my .260 rem instead of a 300 win mag which I didnt shoot well [bleep] woulda dropped like a sack of taters.
Long story short I used to much gun and took to tracking "way" to quick. Lesson learned!
