Jmb ballistics

Ballistic Research Lab reports. Such experimentally-measured data, which include weight, twist, sta-bility factor, bullet length, and velocity, are very hard to find. These 40 examples include all the sporting bullets plus some military ball or solid test projectiles that are readily available from the military litera-ture. These more or less fit into the solid or solid-core ….

Northeast. Aug 16, 2015. #9. bigngreen said: Both jbm, shooter and G7 use the same basic solver so if you a large discrepancy between them you have an input issue and if you have to tweek a Berger g7 number in shooter for 1000 yards you have an issue with an input. I have also found this to be the case.The twist rate (inches per turn) of the barrel. This value is used to calculate stability. It should not be confused with the required twist calculated by Bullet Drag. The diameter of the base of the bullet. For boattails, this is smaller than the caliber. The length of the boattail from the rear of the bearing surface to the base of the bullet.Plastic Tip Length. Length of the plastic "ballistic tip" if it exists. Otherwise zero. Caliber. Diameter of the bullet. Muzzle Velocity. The velocity of the bullet as either (1) measured at some distance from the muzzle or (2) as estimated from reloading data. The on-line ballistics page can correct for the distance to chronograph.

Rifle is a stock remmy w 5.5x20 nf. My previous longish range shooting was typically done w the ballistic recticle scopes., so the dialing in is new for me. Any help is appreciated.The drag function to use to calculate the ballistic coefficients. Most commercial bullets use the G1, but for some long range bullets, the G7 or G8 is typically a better choice. Some military bullets fit the G5 and G6 functions better than the G1.

Don Miller developed this formula as a more accurate way to find an ideal rifle twist rate. Whereas Greenhill was more of a generic formula, Miller's uses more characteristics of a rifle bullet to arrive a a more tailored solution. m = bullet mass in grains. s = gyroscopic stability factor (dimensionless)Sniper's Hide is a community of Snipers of all kinds, focusing on long range shooting, accuracy, and ballistics.

Power Factor Input Data Bullet Weight Weight of the bullet. Caliber Diameter of the bullet Muzzle Velocity The velocity of the bullet as either (1) measured at some distance from the muzzle (see applicable rule book for measuring methods)Calculation of the sectional density is straight forward. For a 300 grain, .338 caliber bullet, the sectional density is: SD = [ 300 gr / (7000 gr/lb) ] / [ 0.338 in ] 2 = 0.375 lb/in 2. NOTE: With the common definition of the sectional density, the units have to be converted when used with drag functions, velocity, etc, to convert the in 2 to ...The drag function to use to calculate the ballistic coefficients.

herald news joliet The 224 Valkyrie is based on the 6.8 SPC rifle cartridge. And because it spits a projectile about the same size as the 5.56 NATO with the much bigger case capacity provided by the 6.8, it does so with ease, effectiveness, and accuracy. In fact, the 224 is known as a longer distance cartridge that remains supersonic way past the 1,000 yard mark ... bustednewspaper miller countyshiny ore clash of clans Ballistics calculations and formulas for small arms. Drag Function Array Conversion. Convert multiple ballistic coefficients and find the best new drag function.In the example, 1.9 raised to the power of 1.83 is 3.237. If the SG of our bullet and gun is 1.4, then the equation becomes: drift = 1.25 x (1.4 +1.2) x 3.237 for a result of 10.52. This means in this example, the bullet will drift 10.52 inches to the left or right depending on which twist the gun barrel has. hextall announcer It's also much more.
