Barrel length: A longer barrel extends the time time interval where chamber pressure acts on the bullet’s mass. Therefore, a longer barrel increases the exit velocity of the bullet and the effective range of the bullet.
Does rifle barrel length matter?
Yes, but mostly it doesn’t matter. Much depends on how heavy your bullets are, and how slow or fast your powder is, but as a rule of thumb, you lose 50 fps for every inch of barrel you chop off. … Competition guns range from 24 inches to 30, because they’re used at ranges up to 1,200 yards.
What does a shorter barrel on a rifle do?
A short rifle barrel offers advantageous because it is lighter and easier to carry than a long barrel. Short barrels are faster to whip into action, too. They are stiffer and thus potentially more accurate. There’s less flex, less harmonic vibration and less muzzle whip.
What is the advantage of a longer barrel on a rifle?
First, velocity. Longer barrels generate higher velocity because the propellant burns more completely. However, there are diminishing returns with extra-long barrels, depending on cartridge, caliber and propellant. It is often said we can expect a velocity change of about 20 to 25 fps per inch of barrel loss.
What is the best barrel length for accuracy?
The best barrel length for accuracy ranges between 16 and 21 inches (40.64 and 53.34 cm). Shorter barrels tend to vibrate convulsively, producing a more consistent and accurate rate of fire. Notably, the energy from each shot is absorbed into the barrel in less time, increasing the accuracy level.
Does length of barrel affect accuracy?
5 Answers. The short answer: Yes, a longer gun barrel improves accuracy. Theoretical accuracy of handguns and rifles is driven by rifling, barrel length, and bullet mass.
What length AR barrel should I get?
It should be kept in mind that legally, the shortest barrel you can get for an AR is 16″. You might be able to get away with a 14.5″ barrel if you pin a muzzle device on it to make the barrel 16″. Moving forward, the 16″ is perfect for any use, extremely reliable and most importantly, it is very accurate.
Is short barrel or long barrel better?
When it comes to pistols, long barrels will help you be more accurate when shooting, give you a longer sight radius, and increase the velocity of the shot. Short barrel pistols will allow for easier handling and concealment.
What is the ideal barrel length for 308?
Our experience has shown that for a . 308 caliber tactical rifle with the overall rifle weight and shooting distances mentioned earlier, a barrel of 24-27″ is optimum in one of the fairly heavy contours we discussed.
How much velocity do you lose with a shorter barrel?
As a general rule, an inch less barrel will cost a bullet between 25 and 50 fps velocity. This varies depending on powder volume and the burning rate of that powder. The more powder and the slower its burning rate, the more barrel volume needed to burn it.
What is the best barrel length for an AR 15?
20″ barrels provide the most consistent performance across the widest variety of loadings. There are plenty of modern specialized loads “optimized” for use in a 16″ barrel, but the 20″ length will still do things better. Aside from the benefits of velocity, the long 20″ barrel gives a balance benefit to marksmen.
Do shorter barrels have less recoil?
With equal quality rifling, the short stiff barrel will win. Recoil: Lots of things going on with it. But longer barrel typically means less recoil. Sound: A longer barrel allows for more propellant to burn which means for a quieter sound along with less flash.
Do longer barrels have less recoil?
All depends on the mass to muzzle velocity ratio. Heavier barrel does mean less recoil, but increasing velocity means more recoil.
What is the best rifle barrel?

How long should a deer barrel be?
While a 26” barrel is lighter and more maneuverable, a 28” barrel is going to be more accurate for long-range shots and should be regarded as perhaps the best all-around barrel length. Keep in mind that choke selection can mitigate the inherent differences between 26” and 28” barrels.
