You're shooting a very loud...# Does barrel length enter into this equation? A bullet with a muzzle # velocity of 1000fps would have much more time to 'overheat' and foul a # 26" rifle barrel than a 6" pistol barrel. # # Perhaps a chart with three variables is required: hardness, velocity # and barrel length.-----
#over into a competition rifle, it was found that the slightly slower muzzle #velocity of the M2, 173-grain match bullet in the M14's 1:12 twist barrel #shot better than in an M1's longer barrel at higher velocity. This meant #that the 173-grain bullet was being spun too fast for best accuracy. But it Aug 30, 2006 · Eventually, as the length increases, the friction in the barrel will be greater than the force of the remaining pressure on the bullet, at which point the speed should drop. I’d like to see data out past that point as a sanity check. SayUncle Says: August 30th, 2006 at 3:17 pm. Ben, I doubt you’ll see a 60 inch AR barrel.

bullet felt much softer and produced smaller muzzle rise. Cleanliness: In rifle caliber testing, velocity always increases with barrel length. With my competition handgun load failing the chronograph test our of a carbine, I had expected more bullet drag with longer barrels as bullets got heavier. However, this turned out to be only partially true. The approximate time that it takes a 3300 fps muzzle velocity bullet to exit the barrel, assuming a constant acceleration, is 0.0011 seconds. 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 ...

Federal 205M primers and H-322 powder was used. Therefore, from the calculation, this bullet would fly apart at or near 307,500 rpm.
The velocity with which it leaves the barrel is known as the muzzle velocity. To understand the motion of the ball, the velocity can be resolved into horizontal and vertical components. Experiments, taking multiple images with strobe light of projectiles, show that the horizontal component of velocity is constant with time.
From this we can now deduce that a change in weapon temperature itself does not affect the velocity of a projectile enough to warrant a significant change in the POI at 100yds. Neither does the clean barrel versus a fouled barrel. Figure 3 Results recorded from the Oehler 35P Chronograph at a distance of 8m from the weapon muzzle. 7.

If a barrel had no rifling and the stock was directly in line with the bore so recoil energy was dissipated straight to the rear (to eliminate muzzle rise) then barrel "whip" should be minimal. The "whip" theory suggests a barrel's thickness and length impacts how much it moves with each shot. Aug 15, 2019 · What You Need To Know About Barrel Length And Velocity: The assumed 25 fps velocity increase per inch of barrel, in most cases, proves a wive's tale. Tests on barrel length/velocity are often very limited in scope and overall add up to simple guesses. Other factors — chamber dimension, bore dimension — also play a role in velocity.
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. Ballistic calculators are a great tool that can help shooters stay on target, and being armed with the general rule of velocity loss per inch of deviation from the test barrel length could help shooters know where to start when they plug in the muzzle velocity into the calculator.
When a muzzle brake is used Jet Effect Momentum = Powder Weight * 1.7 * Muzzle Velocity * (1 – Muzzle Brake Efficiency)^(1/e^.5) Gas exit velocity is estimated at: 1.7 * bullet muzzle velocity An equal and opposite reaction to the jet effect is transferred to the gun. Let's compare the "kick" of an M1 Garand rifle with that of a Steyr Mannlicher Model S rifle. Recoil (kick) is the force applied to the rifle (and transferred to the shooter) during the firing time, the time during which the expanding gasses of the exploding gunpowder are accelerating the bullet through the barrel.
Nov 16, 2020 · 20″ barrels provide the most consistent performance across the widest variety of loadings.

AR-15 Barrel Length - What Length Should You Choose? Is a Longer AR Barrel More Accurate? To sum up barrel length: For most people, it's a 14.5″ (+1.5″) or 16″ barrel for easier handling in close quarters, or an 18″ or 20″ barrel for greater range and muzzle velocity.Question: The barrel of a hunting rifle is {eq}0.87m {/eq} long. When it is fired, the hot exploding gas inside the barrel pushes the bullet until it emerges at a muzzle velocity of {eq}834 m/s {/eq}. The velocity actually decreases slightly from that point towards the muzzle and the bullet exits the 28 inch barrel after about 2.3 milliseconds. Although most match barrels are 28 inches long, there is no advantage in having such a long barrel. This commonly referred to as muzzle velocity. This can be found from the equation . V 2 = Vo 2 +2*a*x (8) Where V is the muzzle velocity, Vo is the initial velocity before firing or 0, a is the acceleration found above, and x is the length traveled by the spud or the barrel length. This yields the following equation. V 2 = 2*a*x (9)
