The hollow point bullets sound lethal. They are likened to a food mixer
ttps://en.wikipedia.org/wiki/Hollow-point_bullet
"In killing, hollow points are designed to increase in diameter once within the target, thus maximizing tissue damage and blood loss or shock, and to remain inside the target, thereby transferring all of the kinetic energy to the target (whereas some fraction would remain in the bullet if it passed through instead)".
I've never unnderstood the argument JB left the rifle out for SC. If it was left out the chances are NB unloaded the mag and returned the rifle and mag to the gun cupboard/den. None of the weapons were locked away so anyone inside WHF had access to them.
1) all bullets are lethal if they hit the right place.
2) Jeremy's claim of leaving the gun out served several purposes:
A) Provides an excuse for his prints to be on the weapon and casings
B) Sheila would be unlikely to go get the weapon herself from the closet and load it. It is much more believable she would get angry and grab a weapon of opportunity. Furthermore, if she did get it out to load it while loading the magazine Nevill could simply take it away because 2 hands are needed to load the magazine.
C) If she did go to the closet to get it then she would have found it with the scope and moderator attached. She would not have removed them herself. Saying he left it out with these accessories unattached made police not seek them out and question why they were not attached. Only much later did police face that he lied about them not remaining attached when it was put away.
The lie and staging the bullets afterwards helped him initially but bit him in the ass later. That is often what happens when you lie unless you make up a lie that is so perfect no one figures out that you lied.
