Speaking from years of experience working as an ER nurse in the Chicago ghetto... He drew a short straw on the weapon of choice. .22 caliber slugs tend to bounce around inside a person. Anything carrying more energy would likely have shattered his scapula, and gone clean through him. The energy of the slug wouldn't have been used up bouncing around his chest. I took care of a person shot in the ankle with a .22. The…

Aside from the ease of sound suppressing them, and the small size of the weapons, there is a reason some of the best hit squads in the world use the .22lr! Admittedly, a .22WMR is pretty much a different animal than the .22lr. Out of a rifle, it would have probably been a through and through, assuming a FMJ bullet -- you'd probably get 2000fps for a 40gr. A JSP might not have, and out of a Ruger Single Six, it's a lo…

Your post is nearly indecipherable for a non-expert.

Yeah, I scrolled down hoping it would say. Remarkable none the less. Makes me very glad (scrap that, thank god) I live in the UK where carrying deadly weapons isn't seen as a right.

Total firearm-related death rate per 100'000 for the US: between 10.2 and 15.22.

For the UK: 0.38 to 0.46

Maybe I'm missing something, but what kind of units are "foot pounds per square inch"? That's definitely not a pressure...

A foot pound is the amount of force required to move a pound of material one foot. By adding a surface area it becomes a measure of pressure.

Any amount of material can be moved any distance with an infinitesimal amount of force, given enough time... or maybe I'm missing something.

It's force per unit area, sounds like pressure.

Uh, isn't a pound-per-square-inch a pressure? A foot-pound-per-square-inch is a rather odd unit of energy.

Yes, a foot-pound per square inch would be a unit of torque per area. Maybe the bullet twisted its way in.

Interesting, but I really don't think this belongs here.

I think his impassive, detailed, technical description/narrative will chime with a lot of people here, in a way that it wouldn't at other communities.

To be fair that's for England and Wales, not the UK.

In Northern Ireland (where as far as I'm aware the gun law is the same) it's 6.82.

It's interesting that England and Wales features in 7th lowest spot for death rate whereas Northern Ireland is 7th highest.

THIS debate definitely does not belong here. Seriously, even if humankind ever does sort out the essentially intractable problem of governmental control over the carrying of lethal weapons by the citizenry, I am willing to bet everything I own that we won't be sorting it out here on Hacker News.

I reckon we could have a fucking boring argument about it though. I've seen it done, it looks easy.

Counterpoint; anyone not in uniform and carrying a gun = criminal.

Deal with accordingly.

(This is definitely one of the debates to avoid here because it is very polarizing, however, for the record we have a pretty good firearms record in the UK)

Not quite; friction has it's say first :)

Foot pounds are a commonly used unit of energy when discussing small projectiles such as bullets, pellets, arrows and bolts. I believe the author's use of "foot pounds per square inch" was an error.

WolframAlpha calculates the energy of a 40 grain bullet at 1550 feet per second to be 213.3 foot pounds, not 324. Winchester claims that a 40 grain .22 magnum bullet from a rifle-length barrel exits the muzzle at 1910 feet per second and has 324 foot pounds of kinetic energy. WolframAlpha agrees.
