unless you know exzactly where that heart is sitting in the cavity, id say hitting it would be a bonus. i know it sits just above the leg...but left side? right side? middle of the cavity?? i dont know...i never looked i just pull them out.

quartering away shots you should try to hit both lungs. if its steep then your looking at passing or 1 lung and liver...

think before you shoot...whats it going to hit going in and coming out?? aim for the exit hole.
