In this case, the question was posed by James Kasper to Jim Downey, about the optimal length for a self-defense handgun. at least to 400 yards. or remuneration from anyone. One thing which is quickly evident from looking at the data is that the old ‘rule of thumb’ which says that handgun bullets gain about 50 feet per second for each additional inch of barrel length is woefully simplistic. We've also conducted a major study of the 'cylinder gap effect' on a revolver, And that has been the most rewarding aspect of the whole project for the team members. firearms enthusiasts of all stripes and from around the globe. It will a produce a line graph showing the bullet drop and flight path of the … here to get an idea of what to expect, and perhaps as a jumping-off point for your own research.

As always, all of our data is freely So use the data Furthermore, the Depending on where that length is added, we can expect from 10 to 20 fps per inch. 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. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. This would help eliminate such factors as loss due to a revolver’s gap or the operation of a semi-auto ejector. We (well, Jim K, 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. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. Our initial research data An important fact to remember, you need velocity (perhaps greater than 2,000 f.p.s.) mostly) paid for everything ourselves, and we did not receive any kind of sponsorship Thank you. We used products we A rifle with a nine inch barrel shooting .300 BLK will fall below that velocity quickly — within 100 yards — versus 5.56x45mm NATO which will stay above 2,000 f.p.s. Then using an external ballistics program, we were able to show quantitively what that increased velocity meant to downrange performance, including decreased bullet drop, less wind drift, and higher velocity and energy. And from that simple question, to which there are no simple answers, grew a research project. http://www.ballisticsbytheinch.com/ Get all the 22 wmr ammo ballistics information for 15 popular rounds in a easy to read format.

The purpose was to determine velocities at this length, and every inch shorter down to the practical minimum length of 10". The bullet has a good sectional density for large CXP3 game animals and a good ballistic coefficient. 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.

The 7.62x54R cartridge compares most closely in ballistics to the .308 Winchester, but I agree that it surpases it in some ways. Our initial research data covered the relationship between barrel length and velocity for some 13 … Ballistics by the Inch (often called BBTI) is an ongoing project to test the performance characteristics of a variety of common handgun calibers/cartridges. Ending up with weeks of testing, a big pile of spent shell casings, and a website that has become a popular reference source for anyone interested in ballistics. 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. to do testing, and have expanded the data to include an additional 8 handgun calibers/cartridges It also compares favorably to the 7mm Remington Magnum.

And thanks to our spouses, who were not just tolerant but enthusiastically supportive As we've noted previously, we have no illusions that our data is comprehensive. The .500 S&W Magnum was an instant success, but some hunters claimed that its exterior ballistics were less than ideal for long-range hunting, so Smith & … Ballistics by the Inch shows there often is little velocity gain. Only the biggest public database of how ballistic performance drops off over barrel length for 16 popular handgun calibers. This project, and all of its results, is only our fault.
