Automatic Pistol Cartridges
Automatic Pistol Cartridges
Automatic Pistol Cartridges. — With the introduction of the magazine pistol special smokeless cartridges have been devised that are rimless and have a crease around the base of the shell by which they may be held and manipulated by the mechanism. These cartridges are exceedingly clean-shooting. Several hundred rounds may be fired without causing more fouling than is apparent after the first few shots. This ammunition is furnished loaded with " full-mantled " and " soft-nosed " bullets; the latter, having the lead exposed at the point will mushroom on striking animal tissue and are sometimes referred to as " dum dum " bullets and are intended for hunting purposes.
The mantled or metal cased bullet has undoubted advantages in rifle ammunition, in which low trajectory and extreme long range are desiderata that can be obtained only by high velocities. In ammunition for magazine pistols and revolvers, however, the prime object is to deliver the most effective blow possible at comparatively short range.
The velocities attainable in large calibers within the permissible weight of an automatic pistol are comparatively low. The deformation of any bullet on striking animal tissue is in direct proportion to its velocity. It is, therefore, extremely doubtful that a metal cased bullet will ever prove as effective and satisfactory in " stopping power" and for military service, either in the automatic pistol or the revolver, as the large caliber lead bullet.
The .25 cal. is the smallest of the American made automatic pistol ammunition and is adapted for the Colt and other magazine pistols. It is an accurate cartridge but the short length of barrel of the Colt weapon makes it impossible to do accurate work with it.
The .32 Automatic Colt is adapted to Colt and other magazine pistols of this caliber. It is an accurate, pleasant shooting cartridge with very little recoil and excellent work can be done with it at the target.
The .35 S. & W. Automatic is adapted to the Smith & Wesson magazine pistol. It is a very accurate cartridge, has no unpleasant recoil and like the preceding is well adapted for target shooting.
The .38 Automatic Colt is the best proportioned and most powerful of all automatic pistol cartridges. It has a slightly flattened point and is extremely accurate. When fired from regulation arms this ammunition is capable of placing ten shots inside a 3-inch circle at 50 yards and inside a y-inch circle at 100 yards.
This was the ammunition of the first Colt automatic pistol introduced in the United States.
Light or gallery charges in magazine pistol shells are impracticable on account of not having sufficient recoil to operate the automatic mechanism. Slightly reduced loads with lead bullets may be used in some of the arms but seldom with satisfactory results. Reduced loads can be used in most of the weapons if the mechanisms are hand operated for each shot.
