Shrubs I am going to ask again what do you want your bullets to do? When you shoot behind the shoulder or if you hit the shoulder? Answer that and I will tell you with one to use.
Just throwing this out there directed at no one. I love how we talk about failed bullets recovered from dead animals.
You have a point, that said, there are situations where follow up shots, tracking, etc are required. Bullets fail and prey do not die, or do die and are not recovered. Some require followup shots and bullets, or wound channels are analyzed later. Shot placement is very important, but only one part of the equation.
Jimmy- I agree with you. My thoughts are most controlled expansion bullets in a 7 mm (and most center fire offerings for that matter) will kill a deer. Dead is dead. I have had bad experiences with Barnes X bullets not expanding at all in wolf, deer, and bighorn sheep. With those bullets I was not ever able to recover a bullet. I also had a complete pass through on a deer shot in the chest facing me at a long distance (not the best shot placement for certain).
Pencil holes does not mean they are not expanding. But I hear you because I am like you and like a little more of an exit. Fist sized would be ideal
