Comparison
A standard .30 carbine ball round weighs 110 grains (7.1 g) and has a muzzle velocity of 1,990 ft/s (610 m/s) giving it 967 ft·lbf (1,311 joules) of energy. By comparison, a .357 Magnum revolver fires the same weight bullet from a 4-inch (100 mm) barrel at about 1,500 ft/s (460 m/s) for about 550 ft·lbf (750 J) of energy, though it is important to note that the .357 bullet is larger in diameter (caliber) and is normally an expanding or hollow-point design. The above comparison is between a full length .30 carbine barrel and a 4-inch barreled .357 handgun.
The .30 carbine was developed from the .32 Winchester Self-Loading used in an early semi-auto sporting rifle; both rounds are comparable to the .32-20 Winchester round used in carbines and revolvers. .30 Carbine sporting ammunition is factory recommended for hunting and control of large varmints like fox, javelina or coyote. The .30 Carbine generates half the muzzle energy of the typical .30-30 Winchester deer rifle round and one-third the energy of the typical .30-06 Springfield big game round. The game laws of several states do not allow hunting big game with the .30 Carbine either by name or minimum muzzle energy allowed.

Famous quotes containing the word comparison:
“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
—Shusha Guppy (b. 1938)
“But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.”
—Ralph Waldo Emerson (1803–1882)
“Most parents aren’t even aware of how often they compare their children. . . . Comparisons carry the suggestion that specific conditions exist for parental love and acceptance. Thus, even when one child comes out on top in a comparison she is left feeling uneasy about the tenuousness of her position and the possibility of faring less well in the next comparison.”
—Marianne E. Neifert (20th century)
