Chuckles' New Stuff

Chuckles wanted a .357 revolver after trying mine a few months ago. He had to get one for himself. And did.

Smith and Wesson. He's glad it came with rubber grips as well as wood, as the wood one punish his hands with magnum loads. The rear sight wiggles. That shouldn't be...

But he's been drooling on the Springfield EMP. I hope he gets one of those, too. He wants something in 1911 design, and likes that little EMP. I'd love it if he got because I could shoot it and decide if I want to get it.

Chuckles has also made up a spreadsheet of various energy ratings or various ammo calibers and self defense rounds. He knows to take the results with a big grain of salt. The data for feet per second is often provide by the manufacturer. There are other variables not taken into consideration as well. He compares that to actual results with water filled milk jugs on the site Box O' Truth, and see that the numbers don't necessarily match up to performance in reality. We all suspect that reality would be further skewed if the targets were flesh and bone and not plastic water jugs. According to the graphs, .38 Special isn't supposed to do that well, but it penetrates more water jugs than you'd figure.

Any, from the energy NUMBERS on his sheet, Speer GoldDot Personal Protection and Federal Hydroshok do pretty well for .45. Middle of the road on energy, not +P, and still on the heavy side. 452 and 413 foot pounds respectively. Corbon did very well in the +P 45s, 165 grains and 575 foot pounds.

Oh and energy equals half the weight in pounds (a grain is 1/7000th of a pound), times velocity in feet per second, squared, times 32.175; and that give you foot pounds of energy, I'm pretty sure.

Based on pure numbers the .357 Sig and Magnum is an awesome cartridge. The Sig is expensive, though. Speer GoldDot .357 Magnum is 583 foot pounds, on his chart. .38s are in the mid 200's.
