These were developed as " companions " to the popular revolvers of the day, firing the same cartridge but allowing more velocity and accuracy than the revolver.

The significant recoil of the M14 when fired in full-automatic mode was seen as a problem as it reduced accuracy, and in the 1960s it was replaced by Eugene Stoner's AR-15, which also marked a switch from the powerful. 30 caliber cartridges used by the U. S. military up until early in the Vietnam War to the much less powerful but far lighter and light recoiling. 223 caliber ( 5. 56mm ) intermediate cartridge.

Many handloaders customize their cartridges to their specific firearms, usually in pursuit of accuracy: they can assemble precision ammunition using cartridge cases that have been fire formed in the chamber of a specific firearm.

For ultimate accuracy and performance, the handloader also has the option of using a wildcat cartridge ; wildcats are the result of shaping the cartridge and chamber themselves to a specific end, and the results push the envelope of velocity, energy, and accuracy.

The manufacturing process of hollow-point bullets also produces a flat, uniformly-shaped base on the bullet which increases accuracy by providing a more consistent piston surface for the expanding gases of the cartridge.

Noted for its fine accuracy and manageable recoil, it remains the most popular revolver cartridge in the world more than a century after its introduction.

It had a slow rate of fire ( although this increased accuracy ), low magazine capacity, used the underpowered and unreliable 6. 5 × 52mm cartridge and was highly prone to jamming.

These later variants were more reliable in battle, although it wasn't until smokeless nitro powders and copper coated bullets were tried out in these rifles in the 1920s that accuracy and 100 % reliability of cartridge case extraction / ejection was finally achieved or discovered by Birmingham ammunition makers ( KYNOCK ).

Because of this power and its excellent accuracy, the. 45 Colt was the most-used cartridge at the time of its introduction, succeeding the. 44 WCF ( or the. 44-40 Winchester ).

To increase accuracy for the Dragunov SVD, the Soviets developed the 7N1 variant of the cartridge in 1966.

The. 45-70 cartridge, for example, was tested by the military for accuracy at ranges of up to 1500 yards, which required 3 degrees of elevation.

There is no problem firing this cartridge in. 357 revolvers, but the long bullet jump makes accuracy difficult.

The 6. 5 × 55mm cartridge was widely used in biathlon competition until 1975 ( when it was replaced by the. 22 Long Rifle (. 22 LR ) rimfire cartridge ), because of its inherent accuracy and historical popularity with the Scandinavian nations who have dominated this sport.

The 6. 5 × 54mm MS cartridge had traits of a hunting round ; even though it had a projectile with a rounded point, it was ballistically efficient, improving accuracy at moderate ranges.

The. 243 is based on a necked down. 308 cartridge case and is known widely for its accuracy, flat trajectory, and relatively mild recoil.

These fired the standard (. 30 or 7. 62mm ) rifle cartridge but featured heavy construction, elaborate mountings, and water cooling mechanisms that enabled heavy and sustained defensive fire with excellent accuracy, but with the cost of being too cumbersome to move quickly.

A similar amateurish characteristic is revealed in Adams' failure to check the accuracy and authenticity of his informational sources.

What Krim ignores, in his contempt for history and for accuracy, is that these magazines, Partisan foremost, brought about a genuine revolution in the American mind from the mid-thirties to approximately 1950.

Since the validity of all subsequent planning depends on the accuracy of the basic inventory information, great care is being taken that the inventory is as complete as possible.

The element is inserted in the discharge circuit in place of the exploding wire, and the calorimetric heating of the element is measured with high accuracy.

It is our lack of extreme accuracy which forces the use of very large yield nuclear weapons.

Sometimes it is necessary to roughly calculate the square inch area of the opening but the calculation can usually be made with sufficient accuracy that it won't affect the final computation.

The bore is unrifled but is provided with an insert tube which is rifled and which, surprisingly, gives pretty fair accuracy even though it's only 3-1/2 inches long.

It is sufficiently small compared with the surface temperature of the anode holder, to make the energy flux radiated from the environment toward the anode holder negligible within the accuracy of the present measurements.

It omits, for example, practically the whole line of great nineteenth century English social critics, nearly all the great writers whose basic position is religious, and all those who are with more or less accuracy called Existentialists.

If high accuracy is required in preflight leveling, it is usually necessary to integrate or doubly integrate the accelerometer outputs ( this also minimizes the noise problem ).

However, skill is required on the part of an operator to level a platform to any degree of accuracy.

The choice of the heading technique is dependent upon the accuracy requirements, field conditions, and the time available to accomplish the heading.

Obviously, the heading accuracy is lessened by such techniques since errors are introduced because of motion of the stand.

One benefit is that the statistical moment calculations can be carried out to arbitrary accuracy such that the computations can be tuned to the precision of, e. g., the data storage format or the original measurement hardware.

Neither G nor M < sub >☉</ sub > can be measured to high accuracy in SI units, but the value of their product is known very precisely from observing the relative positions of planets ( Kepler's Third Law expressed in terms of Newtonian gravitation ).

In 1527 Erasmus threw doubt on the accuracy of ascribing the authorship of this document to Ambrose, and its author is now usually spoken of as Ambrosiaster, or pseudo-Ambrose.

* 2003 – The Human Genome Project is completed with 99 % of the human genome sequenced to an accuracy of 99. 99 %.

Note: because Solar System bodies are never perfect diffuse reflectors, astronomers use empirically derived relationships to predict apparent magnitudes when accuracy is required.

If the fletching is not arranged to induce rotation, it will still improve accuracy by causing a restoring drag any time the arrow tilts away from its intended direction of travel.

The fine mechanical tolerance required for good accuracy pushed him to consider digital solutions.

Since the Bohr model is not perfectly accurate, due to fine structure, hyperfine splitting, and other such effects, the Rydberg constant cannot be directly measured at very high accuracy from the atomic transition frequencies of hydrogen alone.

It includes an English word-recognition engine to aid recognition accuracy, an on-screen keyboard and the ability to fine tune or correct mistakes through a context menu.

If the position of the antennas is not known to sufficient accuracy or atmospheric effects are significant, fine adjustments to the delays must be made until interference fringes are detected.

Thus fine search algorithms such as bisection steps are still required for accuracy.

While the tabloid's main rival, Sun, carried a fine print disclaimer, the WWN never publicly questioned the accuracy of its own stories until 2004, when the paper began stating that " the reader should suspend disbelief for the sake of enjoyment ".

For electromechanical linear actuators used in laboratory instrumentation robotics, optical and laser equipment, or X-Y tables, fine resolution into the micron region and high accuracy may require the use of a fractional horsepower stepper motor linear actuator with a fine pitch lead screw.

There are several variants which improve the accuracy with which lever can be moved, including the " Snail " regulator, in which the lever is sprung against a cam of spiral profile which can be turned, the Micrometer, in which the lever is moved by a worm gear, and the " Swans Neck " or " Reed " regulator in which the position of the lever is adjusted by a fine screw, the lever being held in contact with the screw by a spring in the shape of a curved swans neck.
