I'll trade you my ____ for your Dodge

i used to have a coworker who was a bit of a gun nut

about once, twice a month he would toss out numbers like 1500 round of 9mm and 50.000 rounds of .22

i once asked him what he expected me to do with those .22s in a SHTF scenario and he simply replied "headshots"
The .22 is much better at center mass shots, as they go in and fragment. A lot of times, they won't go through a skull......but if they do they turn the brain into cottage cheese. A .22 Magnum, on the other hand will get the job DONE.
