Since these standard projectile shapes differ significantly the Gx BC will also differ significantly from the Gy BC for an identical bullet. [61] To illustrate this the bullet manufacturer Berger has published the G1 and G7 BCs for most of their target, tactical, varmint and hunting bullets. [62]
G7 (long 7.5° boat-tail, 10 calibers tangent ogive, preferred by some manufacturers for very-low-drag bullets [12]) G8 (flatbase, 10 calibers long secant ogive) GL (blunt lead nose) How different speed regimes affect .338 calibre rifle bullets can be seen in the .338 Lapua Magnum product brochure which states Doppler radar established G1 BC data.
A real-world average G1 BC of around 0.83 or a G7 BC of about 0.42 is commonly adopted by the users of this bullet, for making long-range trajectory predictions using ballistics calculators. [82]
It used match-grade extruded powder instead of the coarser ball propellant and had a 9.8 g (151.2 gr) boat-tailed FMJ jacketed projectile with an air pocket, a steel core and a lead knocker in the base for maximum terminal effect. It had a ballistic coefficient (G1 BC) of approximately 0.411 and (G7 BC) of approximately 0.206. Produced by ...
It has a ballistic coefficient (G1 BC) of approximately 0.351 and (G7 BC) of approximately 0.176. The 7N10 cartridge replaced the previous variants as standard Russian service round and can penetrate a 16 mm thick St3 steel plate at 100 m and 6Zh85T body armour at 200 m.
The bullet has a steel core and has a ballistic coefficient (G1 BC) of approximately 0.304 and (G7 BC) of approximately 0.152. The tip has no distinguishing colour. It can penetrate a 6 mm (0.2 in) thick St3 steel plate at 300 m (328 yd) and 6Zh85T body armour at 30 m (33 yd).
Commercially, reduced-power .277 Fury Elite ball FMJ ammunition using non-hybrid conventional cartridge cases is offered, that fires a 135 grains (8.7 g) projectile with a G1 ballistic coefficient of ≈ .475 at a muzzle velocity of 2,750 feet per second (838 m/s) from a 16-inch (406 mm) barrel.
Samples of mixed alphabetic-Cistercian notation used for foliation in a late thirteenth-century manuscript. Shown are a1 to a6 and g1 to g7. Although mostly confined to the Cistercian order, there was some usage outside it. A late-fifteenth-century Norman treatise on arithmetic used both Cistercian and Indo-Arabic numerals.
