I always shoot them dead square in the shoulders. I have never had to look for one. I know I'm going to catch flak for saying that, but wading around in cactus and rattlesnakes aint fun. When you go with a guide, that is the first thing he will tell you. There's not much meat on a deer shoulder. They bone it out to make hamburger anyway. They are dead before they hit the ground.
As someone who hunts the brush country, you'll never hear flak from me for shoulder shooting. All it takes is to see a 6' rattler to make one see the light.
