Ballistics By The Inch 2.0 is launched

$15,000 ballistics experiment Ballistics By The Inch has added an additional team member and expended another 1500 rounds of ammunition in their quest for ballistics knowledge.

Three more cartridges have been tested: the .327 Magnum, 10mm Auto and .41 magnum. The team have also tested a wide variety of “real world” handguns and carbines to see how they compare with each other and with the test results.

Testing the ammunition.

I was given early access to the updated information and it has been a fascinating read.

Congrats to Jim, Jim, Steve and Keith for the completion of phase two and also a big thank you from me for all your effort.

  • Well, thanks for the mention (again!). Partly thanks to your coverage of the initial launch, we have had over 770,000 hits to the site in just six months – and I see our data (and site) cited a lot around the web. It’s good to see that people can use our data, imperfect as it is.

    Interesting that for most calibers 8″ – 10″ is the sweet spot where you have 90+% of the max speed. Going to “full size carbine” length doesn’t add much.

  • Very interesting stuff! I can’t imagine the time that has gone into that project

  • Today, I went to the beach with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the
    shell to her ear and screamed. There was a hermit crab inside and it
    pinched her ear. She never wants to go back!
    LoL I know this is entirely off topic but I had to tell someone!

  • I like reading an article that will make men and women think. Also, thank you for allowing me to comment!

  • Hello! I simply would like to give you a big thumbs up for the excellent information you have right here on this post. I’ll be coming back to your blog for more soon.
