nearly 20% short of that produced by the 458 Winchester. the various 458s. Several factors contributing to its less than stellar performance in Africa: clumping of its compressed powder charge[2] and use in 20–22 in (510–560 mm) barrel rifles. Those who reload ammunition are able to take advantage of the .458 Lott's performance flexibility to tailor their ammunition to the species of game they wish to hunt. CZ currently produces the CZ 550 American Magnum rifle in that chambering. penetration and impact-effect required to reliably anchor heavy game, one finds new 458 Lott also achieves greater kinetic energy as a result of its higher The specifications published by SAAMI reflect this fact. It is based on the full length .375 H&H Magnum case blown out and shortened to 2.800 inches (71.1 mm).[1]. The resulting cartridge is named the .458 Lott in his honor. bore shooters seems to be the 458 Lott, since it achieves a good 200-300 fps A-Square Lion Load bullet or soft points manufactured for the .45-70 Government fills this niche for the .458 Lott. Necking up the .378 Weatherby to hold .458-inch bullets, Weatherby surpassed the energy figures of the largest cartridges, to create the most powerful cartridge of all. .458 Lott velocities range from 3,000 ft/s (910 m/s) with the 300 gr (19 g) bullet and 2,150 ft/s (660 m/s) with the 600 gr (39 g) bullet. [3], Jack Lott, a big-game hunter and writer from the US, had an adverse encounter with a Cape buffalo in Mozambique in 1959 in which he sustained injuries. The .460 Weatherby Magnum has few peers for stopping dangerous African game. SAAMI recommends a 6 groove rifling contour with each groove being .150-inch (3.8 mm) wide. This is a particular concern outside North America where only particular lines of cartridge powders are available, sometimes of local manufacture. The cartridge's popularity is due in large part to the affordable rifles and the number of readily available rifles which are chamber for the cartridge. understood. The cartridge is designed for the purpose of hunting African dangerous game. It is considered a highly reliable action for its ability to function dependably under adverse and stressful conditions. [25] Lighter, soft point bullets which rapidly expand or fragment at higher velocities are usually recommended for the big cats. 1 Tropical Rifle. This is not due to any This is the real deal. higher velocity than the 458 Winchester Magnum. Weatherby also entered the .458 game in 1957, with their .460 Weatherby Magnum. that these assertions simply do not withstand common sense, repeatable [citation needed] The .458 Lott achieved both these objectives by its lengthened cartridge. Water is the primary substance of life, and constitutes about 90% of the content of all mammals.  I have observed that some "testers" have chosen wood boards or dry newspapers for penetration testing material, and this is a very poor choice, which in no way simulates the characteristics of a bullet impact with animal flesh.  Wood tends to channel the bullet path, and is less demonstrative of the terminal instabilities inherent to non-expanding bullets when impacting game animals, and is thus an inferior material for the testing of bullet penetration characteristics. same bullet at the blistering speeds characteristic of the mighty 460 Weatherby [6], Not finding a cartridge that would fit his needs, he designed a cartridge which he felt would meet his requirements in a dangerous-game cartridge. The performance goal does not just match but exceeds the original performance specifications of the .458 Winchester Magnum. Mar 8, 2013 - .458 Winchester Magnum, .458 Lott and .460 Weatherby Magnum. Most ammunition manufactured for the cartridge is loaded with a 500 gr (32 g) bullet at 2,300 ft/s (700 m/s) which has become the industry standard for the cartridge. The .458 Winchester Magnum is ubiquitous in Africa. The .458 Lott was standardized by SAAMI in 1995 based on specification provided by Arthur Alphin and A-Square LLC. Since Lott was an influential big-game hunter and writer the cartridge gained some attention with professional hunters in Africa. The better ballistic coefficients translate to better longer range performance. The .458 Lott is a .458 caliber rifle cartridge designed for the purpose of hunting large, thick-skinned dangerous game animals in Africa. These requirement reduce the useful choices to solid bullets. Despite all the impressive "science" deployed to reinforce the This capability easily exceeded the performance that was expected of the .450 Nitro Express and the .458 Winchester Magnum. The .450 Watts Magnum is similar to the .458 Lott with the exception of case length which is 2.850-inch (72.4 mm). [8] A-Square also championed the successful SAAMI standardization of the .458 Lott cartridge which took place in 1995. According to Arthur Alphin, the cartridge length was standardized at 2.800-inch (71.1 mm) and the chamber length at 2.810-inch (71.4 mm) because there were many converted rifles in the field that were chambered for the original Jack Lott length. This is due to the erratic ignition and hangfire issues experienced when large capacity cartridges are loaded … When one tests the same bullet at 2300-2400 fps (as The weatherby weighs 10.5 lbs. Distance between lands is .450-inch (11.4 mm) and between grooves is .458-inch (11.6 mm). In comparison, many ammunition manufacturers load the .458 Winchester Magnum to velocities between 2,050–1,950 ft/s (620–590 m/s). Too loud. The cartridge provides a distinct step up in performance over the .458 Winchester Magnum. [3] Most .458 Lott chambers will accept the .450 Watts cartridge as the chambers are reamed to accept a 2.850-inch (72.4 mm) cartridge. speeds above about 1250-1300 fps. .458 Lott, its parent case the .375 H&H Magnum and the .458 Winchester Magnum for comparison. Loaded with lighter bullets with better ballistic coefficients at higher velocities the .458 Lott can be used as a medium-range plains game rifle cartridge.[26]. While the Lott achieves this velocity, the powders used may not be available in most locales. This raises some interesting issues regarding the relationship between Both bores are the same .458 as the .460 Weatherby. to achieve the velocity with heavy bullets that leads to decreases in This led to the creation of a new cartridge named the .458 Express by its designer Dr. Koos Badenhorst. This set-up was then fire-formed in rifle with a .458 Lott chamber. The .458 Winchester Magnum can be fired in the chamber if required. They currently offer the A-Square Hannibal and Caesar rifles chambered for this cartridge. Description.458 Lott 500 Grain Nosler Partition- The .458 Lott is a .458 caliber belted hunting cartridge designed as a replacement for the less powerful .458 Winchester Magnum.It is based on the full length .375 H&H Magnum blown out and shortened to 2.800 inches. deeper penetration, and when the velocities reach the levels common to today's There has been some criticism of the cartridge for its inability to reach the so-called magical 2,300–2,400 ft/s (700–730 m/s) velocity (with some powders) some hunters, especially those who hunt large animals, believe is required for maximum penetration on dangerous game, the end result is that no scientific proof has been made on this subject, and it is likely accepted because of the older bullets that will not retain their weight at high velocity. The cartridge is capable of firing a 500-grain (32 g) bullet at 2,300-foot-per-second (700 m/s) from a 23-inch (580 mm) barrel such as the Ruger M77. What the .458 Lott lacks in velocity and energy compared to the .450 Rigby or the .460 Weatherby Magnum, it more than makes up for by virtue of its versatility. projectiles always generate more kinetic energy they clearly do not produce In South Africa, where the local Denel Somchem powders are readily available, none of the powders have the capability of launching a 500-grain (32 g) bullet at 2,300 ft/s (700 m/s). [6] A similar method was used by David Miller and Curt Crum to create cases for their early custom .458 Lott rifles. pursuit of the heaviest game. Assuming … The Mauser style action has long been favored by African hunters. this all the time in the various attempts, via new calibers, to achieve higher A-Square, Česká Zbrojovka/Brno, Hornady, and Ruger have been instrumental in the cartridge's rise in popularity. With lighter bullets of 300-grain (19 g), it is able to achieve a velocity of about 2,850 ft/s (870 m/s). Winchester reasoned these American hunters … tests will find that those of us who pack a good 45-70 with heavy bullets need What the .458 Lott lacks in velocity and energy compared to the .450 Rigby or the .460 Weatherby Magnum, it more than makes up for by virtue of its versatility. In 1956, Winchester saw an opportunity. The .458 Winchester Magnum can be fired in the chamber in an emergency. don't know how hard the recoil going to be.

Unlike many of the modern .458 caliber dangerous game cartridges like the .458 Winchester Magnum, .458 Lott, or the .460 Weatherby Magnum, the .450 Rigby was designed to operate at more moderate pressures. Due to its development and purpose, the performance of the .458 Lott is often compared with that of the .458 Winchester Magnum. The Lott has no such issues and takes well to lower powder charges. Weatherby guarantees a 1.5 MOA (44mm/100m) accuracy for this cartridge in a Weatherby rifle. If you decide on buying one, just know that it will most likley be sold soon after purchase. A-Square, Double Tap, Federal, Hornady, Kynoch, Norma are among several manufacturers of .458 Lott ammunition. This is due to the erratic ignition and hangfire issues experienced when large capacity cartridges are loaded with small powder charges. The .458 Lott does well with hardcast lead bullets. The reasons why high impact speeds reduce penetration are not well At present, the 465-grain (30.1 g) Triad (Monolithic Solid, Dead Tough and the Lion Load) for the .458 Lott cartridge is available from the company. [2], Prior to the arrival of the .458 Lott there were a few other .45 caliber (11.6 mm) cartridges with similar performance levels based on the full length .375 H&H Magnum case such as the .450 Ackley Magnum, .450 Barnes Supreme, .450 Mashburn Magnum and the .450 Watts Magnum. Since they’re both descended from the .375 H&H Magnum the two cartridges have a similar straight tapered case. [15] The .458 Lott is capable of reaching a velocity of 2,150-foot-per-second (660 m/s) with the 600-grain (39 g) bullet which is greater than the velocity reached by Hornady's 500-grain (32 g) Superformance .458 Winchester Magnum ammunition.

Cape buffalo and rhinoceros, though heavily boned and tough are mostly hunted with soft point bullets although FMJ and solid bullets are chosen by some hunters. Elle fut à ses débuts proposée avec la Winchester modèle 70 « african. bullet and compares the penetration that results from impact speeds varying With lesser FMJ bullets only heart, lung or shoulder shots should be considered. penetration testing. The following article is based on bullet penetration test results as measured in water-saturated penetration materials (wet newspapers). [1] However, it soon became apparent that the .458 Winchester Magnum was not performing as anticipated. Bullets ranging from 300–600 gr (19–39 g) can be loaded for the Lott cartridge. The .450 Barnes supreme cannot be fired in the chamber of the .450 Ackley as there are minute dimensional differences which may prevent the cartridge from chambering. Weatherby, Inc. is an American gun manufacturer founded in 1945 by Roy Weatherby.The company is best known for its high-powered magnum cartridges, such as the .257 Weatherby Magnum, .270 Weatherby Magnum, .300 Weatherby Magnum, .340 Weatherby Magnum and the .460 Weatherby Magnum.The company's headquarters is based in Sheridan, Wyoming. which was a 405 gr (26.2 g) bullet at 1,330 ft/s (410 m/s). The .460 Weatherby Magnum is a belted, bottlenecked rifle cartridge, developed by Roy Weatherby in 1957. The ability to reload ammunition to lower velocities with lighter bullets can provide shooters with ammunition with less recoil than the full power .458 Lott ammunition. And when one tests the same bullet at the blistering speeds characteristic of the mighty 460 Weatherby Magnum, one finds that the penetration achieved is the most shallow produced by the various 458s. [9] Since then there has been a slow but steady movement away from the .458 Winchester Magnum towards the .458 Lott among professional hunters heading to Africa.[6]. is characteristic of the 458 Lott) one finds that the penetration comes up It was a more economical alternative to the English double rifles that were considered the standard rifle type for dangerous game hunting in Africa. Manufacturers such as A-Square have chosen to load slightly lighter bullets 465-grain (30.1 g) instead of the 500-grain (32 g) bullets. Hence, the reason for companies such as A-Square loading the .458 Winchester Magnum and even the .458 Lott with the 465 gr (30.1 g) Monolithic Solid instead of the 500 gr (32 g), which is reserved for cartridges with large powder capacities such as the .450 Assegai and the .460 Weatherby Magnum. For this reason several rifles which were formerly chambered for cartridge like the .375 H&H Magnum and the .458 Winchester Magnum were easily converted to the .458 Lott early on when .458 Lott rifles were only available as a custom offering. However, A-Square and few other ammunition manufacturers provide a ghost shoulder for the cartridge which was not included in the specification as standardized by SAAMI.

Nyati Inc., a big bore ammunition manufacturer, has taken advantage of this flexibility and offers ammunition featuring a 500-grain (32 g) copper jacket bullet at 1,100-foot-per-second (340 m/s). These conversions required no more than a re-boring or a re-barreling and perhaps a magazine extension if required. The .450 Watts can be fired in the chambers of the .450 Ackley Magnum, .450 Barnes Supreme and the .450 Mashburn Magnum chambers. However, the Lott remained fairly obscure at least in the United States until Ruger offered the cartridge in their Ruger M77RSM Mk II rifles to the American public in 2002. Most rugers have a 23" bl, while 460 weatherbys have a 26" bl. These bullets provide better ballistic coefficients than the more common round nose or flat nosed bullets available in this caliber. Furthermore, as the Lott cartridge is in essence a lengthened .458 Winchester Magnum, converting a .458 Winchester Magnum to .458 Lott involves in many cases a simple re-boring of the chamber and if required, a lengthening of the magazine. A .450 Watts Magnum chamber will accept the .458 Lott cartridge without issue. This performance increase provides better penetration and stopping power than the .458 Winchester Magnum against dangerous game. But I am not sure why you really need another 2100 ft.lbs over a 458 lott.

Typically a full-metal-jacketed or monolithic solid type bullet will penetrate more than 40 in (1.0 m) when impacting a dangerous game animal such as the Cape buffalo or African elephant. [8], The manufacture of spitzer style bullets in the .45 caliber has generally been a recent trend. May 8, 2015 - .458 Winchester Magnum, .458 Lott and .460 Weatherby Magnum. While one might not be able to easily find ammunition for the big Weatherby or the Nitro Express cartridges, due to its popularity one would be able to find .458 Winchester Magnum cartridges. This, together with the ability to load the cartridge to lower power levels, easily adds to the versatility of the .458 Lott. [4] He had been hunting with the then new .458 Winchester Magnum. Jack Lott designed the .458 Lott after an unsatisfactory experience with the .458 Winchester and an angry Cape buffalo. 460 Weatherby Magnum. Since there are several rifle actions manufactured that are capable of handling the full length magnum cartridges such as the .375 H&H Magnum, it is not surprising that the .458 Lott has been chambered in several rifles. After World War Two, Americans flocked to Africa to hunt, but the only suitable dangerous game rifles were either special, magnum length bolt-actions chambered for cartridges such as the .416 Rigby or expensive double rifles which fired hard to come by Nitro Express rounds. The older 460 factory ammo at 500gr./2700 ft. per sec./8092ft. In an emergency, the .458 Winchester Magnum can be fired in the chamber of a .458 Lott. do) one finds that such solids produce nearly 6-feet of penetration in wet [6] CZ chambered the cartridge in their BRNO ZKK 602 rifles based on the Magnum Mauser action. The .458 Lott has ample power to spare on these species. Munition d'exception pour la chasse au gros et dangereux gibier africain le 460 Weatherby magnum est disponible sur l'armurerie française avec toute ses caractéristiques balistique.

What the .458 Lott lacks in velocity and energy compared to the .450 Rigby or the .460 Weatherby Magnum, it more than makes up for by virtue of its versatility. assertion that higher speed projectiles are more capable of inflicting the deep from about 1500-fps to 2500-fps, one finds that the higher impact speeds By 1970 Winchester was forced to deal with the clumping of the compressed powder charge which had been resulting in improper ignition and poor performance. penetration. [7][8][16], The straight tapered case of the .458 Lott provides greater flexibility in reloading to lower velocities than bottlenecked cartridges. particular inherent superiority, but due to the 45-70's "inability" [20] This is especially true if the classic brain shot is contemplated when hunting elephant where the bullet must penetrate through the honeycombed bone structure of the frontal area of the elephant's skull. The fire-formed cases were then run through a .458 Winchester Magnum full length re-sizing die with a set off of .125 in (3.2 mm). They also offer intermediate power ammunition for the .458 Lott as well.[17]. This is due to the erratic ignition and hangfire issues experienced when large capacity cartridges are loaded … It drives a 500 … Due to the popularity of the .458 Lott cartridge as a hunting cartridge there are several sources of ammunition. [36] There are only minute variations between these cartridges. Larger volume cases such as the .460 Weatherby Magnum do not do well with powder charges below the recommended minimums. Mauser makes .458 Lott rifles in several models in their M 98 and M 03 Rifle lines.[29]. [19] The range of available bullets provides the flexibility to customize loads for specific game species. I don't know if there's enough meat in the chamber area to have it reamed for the .460. However, the .458 Lott has a longer case length (2.8″ vs 2.5″) and a longer overall length (3.6″ vs 3.34″). Too powerful. These energy and velocity values provide the .458 Lott cartridge a gain of between 50–100 yd (46–91 m) over the .458 Winchester Magnum in distance. Non-Mauser action rifles for the .458 Lott are produced by A-Square, Blaser and Weatherby. An advantage that the .458 Lott offers over voluminous cartridge such as the .450 Rigby, .460 Weatherby or the .505 Gibbs is that it can be easily adopted in rifles actions which are regularly manufactured with little or no modification of the bolt face. This, Water-saturated penetration materials such as newspapers or ballistic gelatin are far superior with regards to their ability to demonstrate the terminal instabilities that typically occur when non-expanding bullets impact live animal flesh. For this reason, it is a much more economical alternative to cartridges which need larger actions types and larger bolt faces. [18] Acceptable bullet weights for the .458 Lott range from 300-to-600-grain (19 to 39 g). CZ's Brno ZKK602 was one of the first rifles manufactured which was chambered for the .458 Lott. [36] A-Square currently loads this cartridge with a 465-grain (30.1 g) bullet at 2,400-foot-per-second (730 m/s).[37]. Larger volume cases such as the .460 Weatherby Magnum do not do well with powder charges below the recommended minimums. Although higher velocity When the impact speeds significantly surpass .458 Winchester Magnum. Both cartridges also use the same .458″ diameter bullet and both headspace off the belt. The .450 Watts Magnum was designed by Watts and Anderson of Washington State. one drives non-expanding solids the deeper they penetrate. The most powerful chambering the the Ruger #1 came in was the .458 Lott and .458 Winchester Magnum. You are looking at $350 to have it rebarreled and a barrel for $350 more. The .458 Lott was designed to be an African dangerous game rifle cartridge particularly for use against heavy, thick-skinned dangerous game such as elephant, Cape buffalo and rhinoceros. Spitzer bullets with better ballistics such as the Barnes X or TSX bullet provides better down range performance over the more conventional .45 caliber (11.6 mm) bullets. It would mean a custom barrel installed by a gunsmith. Premium solid bullets from A-square, Barnes, Hornady, North Fork or Woodleigh weighing in the range of 450–550 gr (29–36 g) are all capable of holding together without much deformation and penetrating to the brain. Larger volume cases such as the .460 Weatherby Magnum do not do well with powder charges below the recommended minimums. about 1600-fps, there is a very definite and measurable decrease in penetration Case capacity and performance is slightly greater than that of the .458 Lott resulting in less 50-foot-per-second (15 m/s) in velocity at equal pressures. The ghost shoulder serves to provide better retention of the bullet in the case under recoil. [1] While the case capacity is slightly more than that of the Lott cartridge, the maximum overall cartridge length is the same. Blah, blah, blah. However strict SAAMI compliant chambers will not accept the .450 Watts Magnum and any attempt to discharge it in such a chamber will invariably result in higher pressures and catastrophic failures may result.

[27] However apart from these species, North American big game does not require cartridges similar to the .458 Lott. The current rage among big Winchester's remedy was to lessen the compression of the powder column. There are few things in the world of ballistics less well The .458 Lott was designed in response to perceived inadequacies and problems encountered with the .458 Winchester Magnum. [21] Bullets which are chosen must have sectional densities of over .300 while a sectional densities of .330 are preferred so as to provide the necessary penetration on these, the largest of the terrestrial mammals. The first cases for the new rifle cartridge were fireformed from .375 H&H Magnum brass into a chamber by using .458 caliber (11.6 mm) bullets which had their bases re-sized .375-inch (9.5 mm) so as to fit in the mouth of the .375 H&H Magnum.
