Happy Thanksgivuk … er, I mean Birthday!
OK, first: Happy Thanksgiving to all my fellow Americans. And Happy Hanukkah to all who observe it!
But most of all,
Happy Birthday to BBTI!
Yeah, it’s our fifth birthday. We officially launched the site on Thanksgiving in 2008. And it’s been a fun romp since then. We’ve gone through many different iterations on the site, adding in more calibers/cartridges, doing the big cylinder gap test, tweaking this and changing that. We’ve shot something on the order of 22,000 – 23,000 rounds. We’ve had something in excess of 20 million hits to the site. We’ve invested more than $50,000 and untold hundreds of hours of labor. And we’ve become pretty much the default resource for anyone who has needed (or just wondered about) data pertaining to handgun ammunition performance over barrel length. Like I said, it’s been fun! Thanks for helping to make it so!
And since it is our birthday, it’s time for a gift in the form of a whole new section to the BBTI website:
From that page:
For years people have wondered about the effects of the different styles of rifling, and whether one or the other would offer specific advantages for accuracy or velocity from a given cartridge. But since many different factors can have an effect on both accuracy and velocity, these discussions have largely remained anecdotal. We decided to see whether we could generate data as to performance differences between the two styles of rifling as concerns bullet velocity, using our standard chop-test techniques. The data on this page is the result of those tests.
Check it out when you get a chance! And thanks again to all who have shared links to our site, who have sent us emails, who have contributed to help offset our costs — you folks have made our success possible, and it is very much appreciated.

PS: as a personal thanks as well, I have made both my first novel and our care-giving memoir available for free download for today and tomorrow (Nov. 28th & 29th).
