Nice little chart for handgun energy:

If you concern yourself or not, that's another matter. But if you do, it's rather helpful.

[Dave R]

Yup. Rather helpful. Shows what a big difference bullet weight makes, among other things.

[Preacherman]

Thanks, Ogre! Very useful information. I downloaded the Excel spreadsheet, and was able to save it in Microsoft Works and Quattro Pro versions without trouble.

[George Hill]

The one thing about this graph that keeps it from being really useful is the bullet's diameter. I believe that to be highly important.

George,
The chart is universal and doesn't depend on caliber.

All it illustrates is that by doubling the weight, you double the energy,,,but if you double the velocity, you quadruple the energy.

[Kamicosmos]

Yeah for example you can apply one bullet wieght to different calibers by velocity. ie 185 grain bullets across 40S&W, 10mm, 45ACP, 41 Magnum, 44 Magnum, etc.

Neat little chart.

[WheelMan]

The top of the chart is a 300 grain bullet at 1800fps. What gets up in that range if anything? .475?

[Jim March]

45-70 leverguns hit that. The 500S&W can probably make it.

[George Hill]

"The chart is universal and doesn't depend on caliber."

True. But Energy has very little to do with a bullet or load's effectiveness. It might indicate which one might penetrate deeper given same bullet type and caliber... but that's about it.

[Hal]

T'is but one small piece of a very large puzzle.

What someone was kind enough to do was translate the energy formula into a graph form for,,,,from what I can see,, handgun weights and velocities.


Here's another link:

which provides a calculator type format to figure energy if you want to figure other non handgun stuff.

WheelMan,
There really is no top of the chart,,so to speak.

[WheelMan]

I understand that, but there is a top to this chart.
