Calibers / Cartridges
Here is a list of all 22 different data sets we have tested. Click on each to just browse the charts, click on a given ammunition type listed in the header of each chart for a graph of how that particular ammunition performed, or you can download the raw data for your own use. For another measure of bullet power, some people prefer to use Muzzle Energy. One of our BBTI readers went through and did all the calculations for this, using our data, and has been kind enough to share this information. You can find his Excel data sheets, with the muzzle energy calculations added in red, on the raw data page, and a link to a muzzle energy graph on each caliber page. Thanks to Jason Coon for this work!
If you think that you discover an error (perhaps a typo) in the data, just drop us a tweet/email or post a comment on the blog - one of us will double-check the original recording sheets.
One note: in every case with the T/C Encore the length of the barrel was measured from the end of the barrel back to the breech face. This is how semi-auto pistols are measured, but revolvers are measured as the length of the barrel in front of the cylinder gap. Take this into consideration when comparing calibers using our numbers.
