In 2009 an additional three calibers were tested and in 2010 and 2011 more calibers were added. The parent case is the .308 Winchester with a narrowed neck that fits a .284 inch bullet on a .315 inch neck with a r… Now it is available free of charge for the average firearms enthusiast to comb through, consider, debate. But to make sure that the data collected was relevant, over 40 actual real world guns were also tested using the same ammunition, and those results included on the website. Once all the ammo was tested at 18″, one inch of barrel was chopped off, and the tests repeated. The purpose was to determine velocities at this length, and every inch shorter down to the practical minimum length of 10". Their average velocity and standard deviation are recorded. Thank you. home       + Welcome to Ballistics By The Inch, or 'BBTI' as people have taken to calling it. Welcome to Ballistics By The Inch, or 'BBTI' as people have taken to calling it.

Going down to a 12-inch barrel only loses another 83 fps, while a 10.5 inch barrel will still fire the 123-grain bullet at just over 2100 fps. In response to the phenomenal popularity of the site, we've continued A research project that grew. Jim Kasper, who started it all with a simple question, and was willing to underwrite the bulk of the $20,000 cost of the project, figured that the data has probably been created before by gun and ammo manufacturers, but that the data had always been treated as proprietary. No further tests will be conducted, but we will maintain this site and data for the use of True Stories? A fast hand loaded 150 grain bullet creates a lung wound less than a quarter inch larger than typical factory loads with exit wounds averaging .75” as opposed to just under or around .5” for factory loads. meant to be indicative - giving an indication to the general relationships between barrel length A 240 grain Federal Hydra-Shok load from a .44 Remington Magnum (.429 inch bullet diameter) carbine nets 1619 fps from a 16 inch barrel, putting the 10mm to shame. Some ammunition maxes out sooner than others in the same caliber. This is still extremely slow for a carbine, for a .22 Winchester Magnum rimfire carbine with a 16 inch barrel shooting 45 grain Hornady FlexTip … James and Jim eventually added in Steve Meyer and then Keith Kimball to their project, starting with thousands of rounds of handgun ammo and custom made 18″ barrels for a Thompson/Center Encore pistol.

As always, all of our data is freely mostly) paid for everything ourselves, and we did not receive any kind of sponsorship or remuneration from anyone. The test protocol for this experiment was the same as the other’s we have done (.223, 7mm Rem Mag, 308, and 300 Win Mag). The T/C was chosen to provide ‘ideal’ data, across cartridges which may traditionally be used in a revolver or a semi-auto handgun. It would be impossible (for us, at least) to test all the different As we've noted previously, we have no illusions that our data is comprehensive. James Downey is the bookbinder of the BBTI team, who has also been a gun owner and avid shooter for almost 40 years.

The recent revisions, which included a new round of tests (going from 13 to 16 calibers), has pushed the site to over a million hits. The 7.62×39 is an ideal cartridge for a short-barreled rifle, provided a bullet that produces good terminal ballistics is used. This would help eliminate such factors as loss due to a revolver’s gap or the operation of a semi-auto ejector. For some calibers, the difference between a 2″ barrel and a 3″ barrel can be almost 400 fps, for others less than 50 fps. Ballistics By The Inch – Home brewed ballistics science that shows that size really does matter – but not necessarily in the ways that everyone has always thought.
