Bullets ranging in weight from 100 gr (6.5 g) to 115 gr (7.5 g) should be chosen for these deer species. Although the .257 Weatherby is used as an elk and moose cartridge with success in North America, the cartridge is thought of as being ill-suited for these heavier deer, with elk weighing on average 700 lb (320 kg) and moose on average ...

The original 38 M41 ball cartridge used a 130-grain full-metal-jacketed bullet, and was loaded to an average pressure of only 13,000 pounds per square inch (90 MPa), giving a muzzle velocity of approximately 725 ft/s (221 m/s) from a 4-inch (100 mm) barrel. [17] [18] This ammunition was intended to prolong the life of S&W M12 and Colt ...
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
