TH, I simply stated if you want an animal to drop like now with a better % shot with a firearm the pins are better than a neck shot. I generally aim for the vitals(rib in and rib out) I have on occasion aimed for the pins or other shots for different reasons but always think secondary like if my bullet frags or malfunctions will I at least get lungs??? I always think lungs when I pull the trigger on a bow or firearm. Simply put it is a gaurantee you take out the lungs that deer is dead on its feet, will leave a nice swash on the ground to track and bleed out the animal somewhat to provide better eating(if you believe in this

). Vitals are essential if I can' t take out the H/L region I simply don' t shoot, their are many ways to the bread basket besides ribs[8D]. This is why I said think like a bowhunter...VITALS
Also poor results with shoulder shots are often due to an improper bullet or sometimes caliber for the job. A 243 shot into a shoulder with a 100 gr NBT is going to yield nothing but bad results on a large whitetail buck, so pick your shot based on your poison and your ability(confidence)[:-]
