Silver bullets differ from lead bullets in several respects. Lead has a 10% higher density than silver , so a silver bullet will have a little less mass than a lead bullet of identical dimensions. Pure silver is less malleable than lead and falls between lead and copper in terms of hardness (1.5 < 2.5 < 3.0 Mohs ) and shear modulus (5.6 < 30 ...
The Winchester Super-X Silvertip consists of a 200-grain (13 g) pointed soft point bullet with an advertised muzzle velocity of 2,490 ft/s (760 m/s), and an advertised muzzle energy of 2,753 ft⋅lbf (3,733 J). [5] Cartridge cases can be formed from .308 cases. [4]
Caliber/calibre: In small arms, the internal diameter of a firearm's barrel or a cartridge's bullet, usually expressed in millimeters or hundredths of an inch; in measuring rifled barrels this may be measured across the lands (.303 British) or grooves (.308 Winchester) or; a specific cartridge for which a firearm is chambered, such as .45 ACP or .357 Magnum.
Silvertip badger, a grade of badger hair used in a shave brush; Silvertip fir, a type of evergreen tree (Abies magnifica) often used as a Christmas tree; Silvertip shark, a large and slender shark (Carcharhinus albimarginatus) found at or close to offshore remote island reefs; Silvertip tetra, a small freshwater fish (Hasemania nana) found in ...
As the power factor calculation is proportional to bullet momentum and as the very large proportion of recoil is proportional to bullet momentum, it is immediately clear that the 9×23mm Winchester had essentially the same power factor and recoil as .45 ACP. The true benefit of the 9×23mm Winchester came from two things.
The wounding potential of a bullet is often characterized in terms of its expanded diameter, penetration depth, and energy. Bullet energies for .380 ACP loads vary from 190 to 294 ft⋅lbf (258 to 399 J). [12] The table below shows common performance parameters for several .380 ACP loads.
Unfortunately, the ballistics of the new cartridge merely duplicated the 246-grain (15.9 g) bullet at 755 ft/s (230 m/s) statistics of the .44 Russian, when the powder capacity of its case would have supported performance rivaling that of the .45 Colt and close to the .44-40.
A hollow-point bullet is a type of expanding bullet which expands on impact with a soft target, transferring more or all of the projectile's energy into the target over a shorter distance. Hollow-point bullets are used for controlled penetration, where overpenetration could cause collateral damage (such as aboard an aircraft).
