Think 357 fmj could still do the job? Deep in the mouth, pointed slightly up? To avoid the hard palate/go thru soft palate. Been reading about locked in syndrome when hitting only parts of the brain stem. The pons. Worried it will ricochet off the tough parts surrounding the brainstem. It's either that or critical defense 38sp hollow points. Worried these won't have enough penetration power. Watched plenty of ballistics videos but these don't recreate the harder tissues surrounding the brainstem. Thanks in advance.
