Just aim half way up right behind the front leg on a broadside shot. It will hit the lungs. The buff may run a few yards and then usually fall over. The lungs are bigger than Robertson shows them.

'Frontal shots are okay but many a client screws it up by not being dead center. Shooting them right where the neck hits the chest will do it.

Many PH's cling to the solid bullet theory, but it is bogus. No need to use solids on buff. I think they just goad the client into solids so they can get in some target practice on wounded buff.

Accuracy? Just don't shoot at distances that you can't hit them!
