Explanation: The .44 Magnum cartridge was developed by lengthening the case of the .44 Special, not shortening it, and loading it to higher pressures.

Explanation: Elmer Keith, a renowned writer and outdoorsman, was indeed a pivotal figure in the experimental handloading process that culminated in the creation of the .44 Magnum cartridge.

Explanation: Elmer Keith's preference for the .44 Special case over the .45 Colt was primarily due to the .44 Special's thicker brass, smaller diameter allowing for stronger cylinder walls, and a more varied selection of projectiles, not solely projectile variety.

Explanation: Smith & Wesson and Remington Arms collaborated in the commercial production of the .44 Magnum cartridge and firearms chambered for it, following successful lobbying by Elmer Keith and associates.

Explanation: The initial prototype of the Smith & Wesson revolver that would become chambered in .44 Magnum was indeed constructed in December 1955.

Explanation: The early Smith & Wesson .44 Magnum revolvers were initially priced at US$140. The figure of $1,600 represents the approximate inflation-adjusted value in contemporary currency, not the original price.

Explanation: Julian Hatcher, serving as the technical editor for *American Rifleman*, provided a review of the Smith & Wesson .44 Magnum revolver and its accompanying cartridge in the March 1956 edition of the publication.

Explanation: Sturm, Ruger commenced development of their Blackhawk revolver for the .44 Magnum cartridge in the summer of 1956, not late 1955.

Explanation: The .44 Magnum cartridge was developed from the .44 Special cartridge, by lengthening its case and increasing its pressure limits.

Explanation: Elmer Keith, a prominent writer and experimenter, is widely credited as a central figure in the handloading experiments and advocacy that led to the development of the .44 Magnum cartridge.

Explanation: Elmer Keith preferred the .44 Special case because its smaller diameter allowed for thicker, stronger cylinder walls in revolvers of the same size compared to the .45 Colt, enabling higher pressures with reduced risk of failure. The greater variety of .44 caliber projectiles was also a factor.

Explanation: Elmer Keith and his associates successfully lobbied Smith & Wesson and Remington Arms to commercially produce the .44 Magnum cartridge and firearms chambered for it.

Explanation: The first Smith & Wesson .44 Magnum revolver was publicly announced on January 19, 1956, following its initial construction in December 1955.

Explanation: The .44 Magnum cartridge originated from extensive commercial handloading experiments conducted by enthusiasts seeking enhanced ballistic performance, notably championed by Elmer Keith.

Explanation: The .44 Magnum cartridge's unofficial metric designation is indeed 10.9x33mmR.

Explanation: Contrary to the designation, firearms chambered for the .44 Magnum cartridge utilize bullets with a diameter of approximately .429 inches (10.9 mm), not exactly .44 inches.

Explanation: The primary functional reason for lengthening the .44 Special case to create the .44 Magnum case was to prevent the higher-pressure Magnum round from being accidentally chambered in older, weaker .44 Special firearms, thereby enhancing shooter safety, rather than solely to increase powder capacity.

Explanation: The .44 Magnum cartridge uses bullets with a diameter of approximately .429 inches (10.9 mm). The '.44' designation is a historical carryover and does not precisely reflect the modern bullet diameter.

Explanation: The .44 Magnum was intentionally designed as a high-pressure revolver cartridge, which inherently addresses safety concerns that arose with older dual-purpose cartridges where high-pressure rifle loadings could be dangerous if chambered in weaker handguns.

Explanation: The .44 Magnum cartridge is a rimmed cartridge, designed primarily for revolvers, although it is also used in carbines and rifles. It is not a rimless cartridge intended for semi-automatic pistols.

Explanation: The primary reason for lengthening the .44 Special case to create the .44 Magnum case was to prevent accidental chambering in older, weaker .44 Special firearms, thereby enhancing safety, rather than primarily to increase powder capacity.

Explanation: The CIP maximum pressure standard for the .44 Magnum is 40,600 psi (280 MPa), which is higher than the SAAMI standard of 36,000 psi (250 MPa).

Explanation: A 240-grain JHP Cor-Bon bullet fired from a .44 Magnum cartridge achieves a velocity of 1,475 ft/s and generates approximately 1,160 ft-lbf of energy.

Explanation: The unofficial metric designation for the .44 Magnum cartridge is 10.9x33mmR.

Explanation: Despite the '.44' designation, firearms chambered for the .44 Magnum cartridge actually use bullets with a diameter of approximately .429 inches (10.9 mm). This designation is a historical convention.

Explanation: The primary purpose of lengthening the .44 Magnum case was to ensure safety by preventing its accidental chambering in older firearms designed for the lower-pressure .44 Special cartridge.

Explanation: The '.44' designation for cartridges like the .44 Magnum is a historical convention stemming from earlier measurements of heeled bullets, rather than a precise reflection of the modern bullet or bore diameter.

Explanation: According to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) standards, the maximum pressure rating for the .44 Magnum cartridge is 36,000 psi (250 MPa).

Explanation: The Cor-Bon 240-grain JHP load generates approximately 1,160 ft-lbf of energy, which is significantly higher than the Remington 240-grain SJHP load's output of approximately 741 ft-lbf.

Explanation: The rimmed, straight case design of the .44 Magnum is a standard feature for many revolver cartridges, facilitating reliable headspacing and extraction from the cylinder.

Explanation: The Ruger Model 44, introduced in 1959, was the first semi-automatic carbine chambered for the .44 Magnum, not a lever-action rifle.

Explanation: Many shooters find that rounded single-action grips, particularly the longer 'Bisley' style, are more comfortable for managing the heavy recoil of .44 Magnum firearms compared to typical double-action revolver grip shapes.

Explanation: When fired from a carbine, the .44 Magnum cartridge achieves significantly higher velocities than when fired from a revolver due to the longer barrel and more efficient powder burn.

Explanation: The .44 Magnum cartridge is known for its substantial recoil, which is not considered very manageable, particularly in lightweight handguns. It is significantly more powerful than cartridges like the .44 Special.

Explanation: The Ruger Model 44 carbine, introduced in 1959, holds the distinction of being the first long gun chambered for the .44 Magnum cartridge.

Explanation: The source suggests that the longer 'Bisley' style single-action grip is often considered ideal for managing the heavy recoil characteristic of .44 Magnum firearms.

Explanation: When fired from a carbine, the .44 Magnum cartridge achieves significantly higher velocities compared to when fired from a revolver, owing to the longer barrel and more efficient powder burn.

Explanation: Firearms chambered in .44 Magnum are generally capable of producing groups of approximately 3 to 4 inches at 50 yards with most types of ammunition, indicating good typical accuracy.

Explanation: The full-powered .44 Magnum is generally considered unsuitable for routine police work primarily because its significant recoil and muzzle blast make rapid fire difficult and strenuous for the user.

Explanation: The .44 Magnum cartridge is indeed considered well-suited for hunting medium-sized game, including animals up to the size of elk, and has even been used on larger game with appropriate shot placement.

Explanation: Heavy, flat-point bullets used in .44 Magnum loads are generally less prone to deflection when passing through light brush compared to lighter, pointed bullets, making them more reliable for accurate shot placement in wooded environments.

Explanation: The primary limiting factor for the .44 Magnum in hunting beyond close range is not its terminal ballistics, but rather the bullet's trajectory (drop) at longer distances.

Explanation: Experts typically recommend limiting hunting ranges for the .44 Magnum to approximately 100 yards (91 meters) due to the bullet's trajectory, not exceeding 150 yards.

Explanation: The substantial recoil and muzzle blast associated with full-powered .44 Magnum loads make rapid fire challenging, rendering it generally unsuitable for routine police duties where quick follow-up shots may be necessary.

Explanation: The primary limitation on the effective hunting range of the .44 Magnum cartridge is the significant drop of its heavy bullets at longer distances, rather than issues with terminal ballistics or accuracy at moderate ranges.

Explanation: The .44 Magnum is considered well-suited for hunting medium game up to elk size. It has also been documented for use on larger animals such as Cape Buffalo and elephants, provided precise shot placement and appropriate ammunition are employed.

Explanation: Heavy, flat-point bullets used in .44 Magnum loads offer an advantage in brushy terrain as they are less susceptible to deflection by twigs and brush compared to lighter, pointed bullets, thus improving the likelihood of accurate shot placement.

Explanation: The prominent use of the Smith & Wesson Model 29 in the film *Dirty Harry* led to a substantial increase in public awareness and market demand for both the .44 Magnum cartridge and the firearm itself.

Explanation: The practice of offering firearms in the same caliber for both handguns and rifles is not a recent development; it has historical precedents dating back to the American Old West, such as the .44-40 Winchester.

Explanation: Demand for the Smith & Wesson Model 29 surged significantly after the release of the film *Dirty Harry*, leading to shortages and increased prices.

Explanation: The iconic movie line 'the most powerful handgun in the world' is famously associated with the .44 Magnum cartridge as spoken by the protagonist in the film *Dirty Harry*.

Explanation: While cartridges like the .454 Casull, .460 S&W Magnum, and .500 S&W Magnum have surpassed the .44 Magnum in power, the .44 Special, its parent cartridge, is significantly less powerful.

Explanation: The .44 Magnum maintains its popularity because it strikes a favorable balance between significant power and shootability, offering more manageable recoil compared to some of the ultra-powerful cartridges that have since been developed.

Explanation: The .44-40 Winchester cartridge serves as a historical example of a cartridge offered in both handguns and rifles, a practice continued by cartridges like the .44 Magnum.

Explanation: The film *Dirty Harry* generated immense popularity for the Smith & Wesson Model 29, resulting in severe shortages and a dramatic increase in its market price.

Explanation: During periods when the Smith & Wesson Model 29 was difficult to obtain, customers often sought alternative .44 Magnum handguns, such as the Ruger Redhawk.
