Studies of bullet SPEED!
I was recently referred to a wonderful site devoted to ballistics with regard to barrel length, ammunition, and bullet speed:
http://www.ballisticsbytheinch.com/ It was one of the most thorough and scientific (and down-to-earth!) studies I have ever seen. My SPEED questions: - Are there any other great sites you can recommend concerning bullet speed with regard to other ballistic factors such as expansion & mushrooming, clothes, distance, etc. ? - Are there any ADVERSE effects of bullet speed, such as premature mushrooming, fragmentation, etc. that have been well documented or from your personal experiences? Thank you!

Well, I used to blow up bullets fairly regularly as a trick, firing thin jacket .22 Hornet bullets out of a .22-250. The bullet vanishes in a puff of lead dust, disrupted by centrifugal force.

http://www.brassfetcher.com/ is good for ballistic gelatin testing.
http://www.theboxotruth.com/ is good for penetration and urban legend testing. Unjacketed lead bullets can make a real mess in the bore and spooky things can start to happen if they are driven at too high a velocity. Copper jacketed lead bullets start to disintegrate in flight once you start to drive them around 4000 fps or so. |

You really made my week with this link: http://www.theboxotruth.com Denim over waterjug tests (with the acceptance that 4 jugs = 12 inches of BG) in which they fetch the bullet to show you the expansion, make more sense to me than fancy-laboritory smoke-and-mirror tech tests. Any more great links like this? Thanks so much!

Sounds like your interested in terminal ballistics. The site I'll
refer you to has a very complete and on going forum about that topic. It will take you quite a while to get through just the stickies. Have fun ! http://www.m4carbine.net/forumdisplay.php?f=91 |

Big thanks to Carne Frio
Carne Frio:
Terminal and wound ballistics are lagely overlooked sciences, and I might have continued to overlook them, had you not brought them to my attention! A big thanks to you!

Too bad they only have done handgun calibers...

It is very hard to make more than general statements (CNS hits are often good stoppers) and observe effects based on ballistic gelatin testing (ever been attacked by gelatin?). The variability of the path a bullet takes in actual tissue is a confounding effect very hard to sort out. |
