16 sie 2021 · First, generally speaking, velocity will increase with barrel length, but not always. Sometimes a shorter barrel will produce higher speed than the longer barrel. Second, you can get significantly different speeds with barrels of the same length.
24 lip 2018 · Barrel Length: 3 to 4.6 Inches. Comparing 17 loads, out of two revolvers, with 3- and 4.6-inch barrels, I found that seven of the loads produced a lower velocity from the longer barrel....
15 sie 2019 · On average, the velocity increase from a 3-inch to a 16-inch barrel was 487.7 fps, which works out to 37.51 fps per inch of barrel. That’s closer to the assumed 25 fps per inch of barrel most expect to see. But here, again, that’s not a reasonable depiction of the difference.
This page will examine barrel length to velocity differences for various calibers. We'll mostly stick to more common calibers, but others will be added as well. Data will be sourced from various sources.
Pistol Barrel Length vs. Velocity (Power) In pistols, there are rapid gains from a barrel at least 3" long : 10% or more per inch. Beyond that, there are diminishing returns.
13 mar 2017 · With .38 Special, and especially with .357 magnum, conventional wisdom says that barrel length has a huge bearing on the effectiveness of the bullet. The longer the barrel, the greater the velocity, and for self-defense rounds, higher velocities often translate to better penetration and expansion.
Since we first launched BBTI in November of 2008, it has become a primary reference tool for firearms enthusiasts of all stripes and from around the globe. Our initial research data covered the relationship between barrel length and velocity for some 13 common handgun calibers/cartridges.
