• Nov 03, 2008 · There is no answer to your question as asked. Cannon are sometimes listed by bore diameter and barrel length in multiples of the caliber, a barrel of 1 caliber would be equal to the diameter of the bore. In such a case, the defining factor would be the instantaneous pressure applied to the bullet.

• Apr 10, 2013 · The muzzle velocity from a 16″ barrel of 2215 fps direct from AAC will be used as well for this comparison. The following chart shows the muzzle velocity from 0 to 500 yards using the Hornady Ballistics Calculator.
• If the barrel twist rate and the bullet length are known then enter those values and click the button to calculate the muzzle velocity. This formula will be used to make the calculation: SF1 = 30 * G ÷ T ² ÷ D ³ ÷ L ÷ (1 + L² );
• Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? Just enter your bullet weight below and its velocity. This calculator will display the foot pounds of energy, and help you compare the power of different loads.
• Nov 01, 2011 · The G17L's 6.02 inch barrel is the most obvious departure from other Glocks giving the G17L an overall slide length of 8.85 inches. This is an instance where size does matter. The longer barrel generates more velocity for the 9x19, especially with +P or +P+ loads.
Manufacturers post a muzzle velocity from a test barrel. Those test barrels can be from 18 to 24 inches for rifle ammo and usually 4 to 5 inches for pistol ammo, depending on the manufacturer. They have no way of knowing what your barrel length is. Of course, as a general rule, a longer barrel will allow for a greater velocity (to a certain point).
The N-133 curve was scaled to generate muzzle velocities of 3287 and 3364 fps in a 22 inch barrel to duplicate the average muzzle velocities that Esten measured during the Test 1 testing. Later the curve was scaled to duplicate the muzzle velocities of each 4 shot group in Test 2.
Dec 23, 2008 · When a bullet manufacturer rates on for a twist, they are usually talking long barrel (= or > 16") and factory typical muzzle velocities. Muzzle velocity of M193 is typically 3250 fps. I typically go a little slower for shorter barrels and faster twists 1:7 or 1:8 and go for right at the 3,200 for longer barrel slower twists, 16" to 24" 1:9 to 1:12. Oct 27, 2017 · 22 Nosler is all about pushing maximum velocity with a 22 caliber projectile from an AR-15 with minimal required changes to the rifle. With just a barrel and magazine swap, you can push a 55 grain projectile from a 22 Nosler AR-15 with a gain of 20% more muzzle energy compared to .223 Remington: a significant boost.
The ballistic curve of an air gun pellet describes the trajectory of the pellet after it leaves the barrel. The trajectory depends on many factors: muzzle velocity, firing angle, mass of the pellet, gravity, and air resistance.

Test barrel: 610 mm (24"), 1 in 12" twist Primers: Large Rifle Cases: Lapua, trim-to length 51,00 mm (2.008").
Feb 15, 2016 · Barrel bore: 7.62: mm: Case Length: 51: mm: Chamber Bore: 11.53: mm: Barrel length: 609.6: mm: Bullet Mass: 147: grains: Aspect Ratio: 3.65: L/Bore: Burn length: 23.6: mm: Projectile Caliber: 7.62: mm: Total Accelerated Mass: 147: grains: Expansion Ratio: 2.2: expansion: Projectile Load: 1 The velocity of sound in 416 stainless steel is 14,900 fps and a stress wave has time to propagate up and back the full length of the barrel 4 or more times after ignition and while the bullet is traveling within the barrel. The muzzle end of the barrel has ample time to "know" that something is going on at the breach end before the bullet exits.
