You know... I never once stopped to figure out if it was 25, 26, 36, or 46 degrees. If the picture I saw said I could make the shot I'd let it fly. You got to know your abilities, the abilities of your equipment and the anatomy of the critter you're hunting. Being a heavy boned bugger like an elk takes away a lot of shots I take with a whitetail. I would never take a shot simply because I felt if he turned he's in the brush. Either I have a shot or I don't. If I don't,.... I wait for a better one. If it doesn't come(which happens a lot) you just don't get the shot. I've waited and often been surprised with a shot better than I could have imagined in my wildest dreams. I wouldn't care if it was the biggest bull elk or a cow... the shots the same.
