A well placed shot centered in the neck drops'em on the spot. A low neck shot and pack your lunch,you will nave a long day,and may not find the animal.Shoulder shots anchor the animal but will destroy a lot of roast.Use some marksmanship,put the shot in the crease,blow out the lungs,with a caliber that will leave a good exit wound,the animal goes into instant shock, and will not be far away,with a blood trail that my 5 year old grandson could follow.
