How much velocity does a 308 lose per inch of barrel?

308 Win factory ammunition were chronographed at each barrel length. READ RifleShooter.com . 308 Win Barrel Cut-Down Test Article. Summary of Findings: The average velocity loss per inch, for all four ammo types combined, was 22.7 FPS.

Does a shorter barrel increase muzzle velocity?

In some instances, the powder may not have even been fully burned in guns with short barrels. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. This greatly increases the muzzle velocity.

What length barrel is best 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.

What is the best barrel length for a 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. Closer ranges or other considerations might dictate a shorter barrel.

Do suppressors increase muzzle velocity?

A suppressor will typically increase the muzzle velocity of ammunition and maintain if not improve shot group. The silencer is enabling the shooter to be more accurate by providing a much less violent platform to operate.

Are fluted barrels less accurate?

Practical Takeaway. By all accounts, fluting a barrel has little effect accuracy, either positive or negative. If done properly by a skilled gunsmith, fluting may lighten your rifle a bit, and it may have a subtle impact on the rifle’s accuracy, possibly a positive one.

Why is the 308 a sniper rifle?

The . 308 is by far the most popular sniping round, and for good reason. The . 308 is not punishing to shoot, has excellent terminal ballistics, behaves predictably in the wind, and perhaps most important is that it is consistent.

What is the best barrel length for 308?

How many rounds can you put through a 308?

308 would get re-barreled around 6500 to 7000 rounds. Accuracy and a tad of velocity starting dropping off at 4500 rounds or so.

Does a moderator reduce muzzle velocity?

Moderators are occasionally referred to as silencers, but this is a misnomer as it’s impossible to silence the report of a high-velocity bullet completely. It does not, of course, reduce the crack of the bullet, nor does it have any significant effect on velocity.

Does a fake suppressor do anything?

Although fake suppressors don’t perform like the real thing, they do provide some benefits for gun owners: While they provide no actual tactical value, the installation of a “can” on the muzzle can make the gun appear more formidable.

What is the optimal barrel length for a 308?

Many years ago, experts at Shilen barrels and top benchrest shooters did extensive experiments and discovered that a 22″ barrel is the absolute best length for accuracy. This is the best length for a .308 barrel as far as accuracy and in addition is is easier to carry through the woods because of its shorter length.

What is the best 308 barrel?

A favorite among police and military forces, the Remington 700 AAC-SD is a strong choice for the best 308 rifle in terms of tactical use. Its 20 inch varmint barrel makes it a great choice for close and mid-range shooting, and its accuracy is fantastic.

What is the speed of a 308 bullet?

The speed of a 308 caliber bullet is from about 2600 feet per second to about 2800 feet per second.

How do you calculate the energy of a bullet?

You can compute the kinetic energy of a bullet by squaring the velocity and multiplying it by the weight of the bullet in grains. Then, divide the product by 450,400: (velocity2 x bullet weight)/450,400.
