So a while back, I was workin’ my ass off on Project X and a buddy shoots me a link and says, “Hey, look! Some game blog has an article about guns!”
So of course, I clicked… and read it. I learned that it was written by a fellow claiming to be a former sniper… blah blah blah… Imagine my joy when I find this gem in the article:
“The .38, 9mm and .357 is the same bullet. The difference is the casing. The 9mm has a longer case then the .38, the .357 is longer than the 9mm. What this means is more powder behind the bullet and an increase in velocity. So .38 bullet travels slower than the 9mm bullet which is leaving the barrel at a slower rate of speed then the .357. “
What the hell did I just read???? Hold on. I am gonna go back and read it again. You do the same. Meet back here when we’re done, and we’ll see if we’re delusional or if spec ops snipers are really this damned ignorant.
Military snipers are in fact that ignorant. How ignorant?
That is a picture of a .38 special next to a 9mm. The case on the .38 appears to be longer than the total length of the 9mm, bullet and all! (it actually isn’t though). Oh, and are they the same bullet? No. That .38 is a 130 grain hollow point. 9mm full metal jackets are 115 grains.
Honestly, a quick check of Infogalactic lists the case length of a 38 special as 1.155 inches.
IG also lists the case length of 9mm as .754 inches.
So given this, why is the 9mm pushing a bullet of similar weight faster? Well, the short answer is that the 9mm is a much more modern cartridge, burning modern powders. The .38 special was introduced in 1898. Savvy?
The maximum pressure for a .38 special is listed at around 18,000 PSI. Compare that to the 9mm which is listed at 35,000 psi. This just in: 35,000 psi is a lot more than 18,000 psi, and you don’t need to talk to a physicist to understand why one of those bullets is moving a lot faster than the other.
The 9mm is maxing out at pressures that are about the same as the max pressure for a .357 magnum.
And now, I hope you understand why you shouldn’t be going to Game blogs to get information about firearms.
We have gun blogs for that.
