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 cartridge delivers accurate (sub-MOA) performance from a sniper rifle. The Lost River Ballistic Technologies/Jamison International 419-grain (26.95 g) very-low-drag bullet is the standard, long-range sniping load. Lost River Ballistic Technologies also designed a 305 grain (19.76 g) bullet for the Battlefield Domination Round (BDR).
The 7mm-08 with 139-140 grain loads does well against some 150-grain .308 Win. loads, providing good energy levels. One example is the Remington 7mm-08 140 PSP (1490 fpe at 300 yards) compared with the Remington 308 150 grain PSP (1344 fpe at 300 yards). [14] The 7mm-08 invites a ballistic comparison with the veteran, highly esteemed 7×57mm ...
Power Level I duplicates the .30-06 Springfield, Power Level II that of the .300 Winchester Magnum and Power Level III is the full power load. Remington offers the full power (Power Level III) .300 Remington Ultra Magnum ammunition in 150 gr (9.7 g) at 3,450 ft/s (1,050 m/s), the 180 gr (12 g) at 3,250 ft/s (990 m/s) and the 200 gr (13 g) at ...
Loaded with more aerodynamic very-low-drag bullets such as the traditionally lead-cored 19.44 g (300 gr) Lapua Scenar GB528 VLD bullet (G1 BC = 0.736) or the Lost River Ballistics J40 .338 17.5 gram (270 gr) CNC manufactured mono-metal bullet (G1 BC = 0.871) the long-range performance and supersonic range of .338 Lapua Magnum rifles can be ...
