The QuickLOAD interior ballistics predictor program also contains the external ballistics predictor computer program QuickTARGET. QuickTARGET is based on the Siacci/Mayevski G1 model and gives the user the possibility to enter several different BC G1 constants for different speed regimes to calculate ballistic predictions that more closely ...
A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1]
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
For greater clarity, most if not all modern, commercially manufactured bullets are based on i = (2 ÷ n) * the Square Root of ((4 * n - 1) ÷ n) to compute the coefficient of form (i) found most prominently in Edgar Bugless and Wallace H. Coxe, series of ballistic charts called "A Short Cut to Ballistics" published by the DuPont Co. However ...
It is excellent for any North American big game in woods or brush, if the 250 grain bullet is used, but not especially suited to long range (400 yards and beyond) as a result of the need to use flat-nose bullets due to the Model 71's tubular magazine. Until Hornady's FTX flex tip pointed bullets, 300 yards with a good peep sight is a fairly ...
Also the muzzle energy is only an upper limit for how much energy is transmitted to the target, and the effects of a ballistic trauma depend on several other factors as well. There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 ...
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
Winchester's factory ammunition for the .300 Winchester Magnum is capable of 990 m/s (3,260 ft/s) with the 150-grain (9.7 g) bullet and 910 m/s (3,000 ft/s) with the 12-gram (180 gr) bullet, however old Western "Power Point" soft point can reach past 1,000 metres per second (3,400 ft/s) with 9.7 g (150 gr) projectiles. The maximum point blank ...
