Values courtesy of the Hornady Ballistic Calculator [14] For the purposes of this comparison barrel a barrel length of 24 in (610 mm) is used. The .458 Lott is able to attain over 2,300-foot-per-second (700 m/s) with a 500-grain (32 g) jacketed bullet at safe pressure levels from a 23–24-inch (580–610 mm) barrel.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...
Winchester's 200 gr (13 g) Ballistic Silvertip ammunition (SBST338) retains over 1,600 ft⋅lbf (2,200 J) at 625 yd (572 m) and has 1,000 ft⋅lbf (1,400 J) energy at 800 yd (730 m). Winchester's Combined Technologies Accubond ammunition (S338CT) extend the range for these energy levels even further to 675 yd (617 m) and 850 yd (780 m ...
Winchester offered factory loaded .256 Magnum ammunition (and brass to reloaders) into the beginning of the 1990s. Winchester .256 factory loads used a 60 grain Open Point Expanding bullet at a MV of 2760 fps and ME of 1015 ft. lbs. from a 24-inch rifle barrel. That is about 500 fps faster than Winchester factory loads for the old .25-20 cartridge.
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 ...
The first AR-15 rifles used a barrel length of 20". In the case of the 223 Remington (M193), ammunition loses or gains about 25.7 ft/sec (7.8 m/s) for each inch of barrel length, while 5.56×45 mm NATO (M855) loses or gains 30.3 ft/sec (9.2 m/s) per inch of barrel length. [18]
The average ballistic coefficient of the 419 grain (27.15 g) is 0.945 over 3,825 yards (3,500 m). Jamison International stated the G1 BC of this bullet on their websitein 2009 at 0.940. Currently (2024) the average ballistic coefficient of the 419 grain (27.15 g) is stated by CheyTac USA at 0.949 over 3,500 yards (3,200 m). [14]
These formulae produce the projectile velocity at range, drag and trajectories. The modern day commercially published ballistic tables or software computed ballistics tables for small arms, sporting ammunition are exterior ballistic, trajectory tables. [49] [50] [51] The 1870 Bashforth tables were to 2,800 ft/s (853 m/s).
