re: Guns
@kazriko if you can manage a 2” grouping with 10 rounds at 10 yards using a larger gauge firearm by all means, use it (I do exactly this with 9mm).
But a lot of people can’t, because they lack the strength, dexterity, stamina, etc. to train with a larger weapon and wield it in an emergency situation.
Almost anyone can achieve this with sufficient training and practice using a .22 pistol. Quality .22 ammunition will penetrate 12” at 10 yards with a 4” barrel, and a 2” group of ten in the body will find at least a couple that make it to vital organs or between ribs and through lungs. If you’ve ever seen someone try to keep moving with a pneumothorax you know how effective this is.
That said I’m getting bored with this “ballistics bench racing”.

@pjsliney this is a decent article on the subject by someone who knows all about shooting people (a cop).
