It was intended as a ballistic upgrade option for the Mauser Gewehr 98 rifles that were standard issue in the German military. The German military chose, however, to stay with their 8×57mm IS rifle cartridge avoiding rechambering their service rifles for a cartridge that, due to its more favourable bore area to case volume ratio, would ...
The .280 Remington is capable of developing energy nearly equal to the .30-06 Springfield, but with lighter bullets having a better ballistic coefficient. The .30-06 produces more energy than the .280 with bullets heavier than 180 grains, though .284" 175-grain bullets have a high sectional density of .310, compared to the 30-06 180-grain ...
Another alternative cartridge that provides slightly improved ballistics over the .7mm Rem Mag, is the 7mm Weatherby Magnum, which though released to the market 18 years before, never reached the popularity of the former, mainly because of Weatherby rifles' high price and since the barrels for Weatherby's cartrdige initially had a 1:12 twist ...
An overview of 7mm caliber cartridges, their history, and uses in firearms.
(Round balls lose velocity faster than conical bullets and have much steeper ballistic trajectories beyond about 75 yards or 69 metres) In contrast, a 4-bore express rifle often used a 1,500-grain (3.43 oz; 97.20 g) bullet wrapped in paper to keep lead buildup to a minimum in the barrel. In either case, assuming a 4-ounce (110 g) mass for a 4 ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.
The difference in velocity between the 7mm SAUM cartridge and the 7mm Winchester Short Magnum (WSM) is less than 50 feet per second; they are almost ballistic twins. Both the 7mm SAUM and the 7mm WSM achieve optimal ballistic results when using bullet weights from 120 to 160 grains.
Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.
