.257 Roberts
.257 Weatherby Magnum
.260 Remington
The .260 Remington (also known as 6.5-08 A-Square) cartridge was introduced by Remington in 1997. Many wildcat cartridges based on the .308 Winchester case had existed for years before Remington standardized this round. Because 6.5 mm (.264") bullets have relatively high ballistic coefficients, the .260 Remington has seen success in rifle competition including bench rest, metallic silhouette, and long range. It is capable of duplicating the trajectory of the .300 Winchester Magnum, while generating significantly lower recoil.[1] Also, converting a rifle chambered for the .308 Winchester (or any of its offspring, such as the .243 Winchester, 7mm-08 Remington, .358 Winchester or .338 Federal) to .260 Remington generally requires little more than a simple barrel change.

.300 WSM
The overall cartridge length is 72.6 mm. The cartridge case length is 53.34 mm. The bullet diameter is .308 in (7.82 mm), which is common to all U.S. .30 caliber cartridges. The principle at work in the short magnum cartridge is the fitting of larger volumes of powder in closer proximity to the primer's flash hole, resulting in more-uniform ignition. .300 WSM has a case capacity of 80 grains. The .30-06 Springfield holds 69 grains; .308 Winchester holds 56 grains; 30-30 Winchester holds 45 grains. The .300 Winchester Magnum has a case capacity of 93.8 grains. While providing ballistic performance nearly identical to that of the .300 Winchester Magnum, 300 WSM does this with about 14 grains less powder. The .300 WSM also head-spaces off of the case shoulder, versus the older .300 Winchester Magnum's belted head space design. The advantage to this round is the ballistic performance is nearly identical to the .300 Winchester Magnum[2] in a lighter rifle with a shorter action burning 8 - 10% less gunpowder. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of the employed firearm. Also, in small ring actions the larger chamber diameter removes more steel from the barrel tenon, making it weaker radially. Source: https://en.wikipedia.org/wiki/.300_Winchester_Short_Magnum
.300 Remington Ultra Mag
.303 British

.338 Win Mag
.338 Lapua Magnum
.458 SOCOM
The .458 SOCOM (11.63×40mm) is a moderately large round designed to work in an AR-15 platform. This is achieved by installing a 458 bolt and barrel. The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft·lbf (3,261 J),[1] similar to a light .45-70 but with a much smaller case.

50 Action Express
The .50 Action Express (AE, 12.7×33mmRB) is a large-caliber handgun cartridge, best known for its usage in the Desert Eagle. Developed in 1988 by American Evan Whildin of Action Arms, the .50 AE is one of the most powerful pistol cartridges in production.[5] Source: https://en.wikipedia.org/wiki/.50_Action_Express

.454 Casull
The .454 Casull is a firearm cartridge developed in 1958 by Dick Casull, Duane Marsh, and Jack Fullmer. It was introduced in November 1959 by Guns & Ammo magazine. This cartridge is a lengthened and structurally improved version of the .45 Colt case. It gained popularity when Freedom Arms released a single-action five-shot revolver chambered in .454 Casull in 1983. Ruger followed suit in 1997 with its Super Redhawk, and Taurus introduced the Raging Bull model in 1998 and the Taurus Raging Judge Magnum in 2010. While the .45 Schofield and .45 Colt cartridges can fit in .454 Casull chambers, the reverse is not possible due to the lengthened case, similar to the relationship between .38 Special and .357 Magnum cartridges, as well as .44 Special and .44 Magnum cartridges.

.44 S&W Russian
The .44 Russian, also known as the .44 S&W Russian, is a black-powder center-fire metallic revolver cartridge developed and produced by Smith & Wesson in 1870. The .44 Russian design marked the first use of an internally lubricated bullet in modern firearm ammunition.
.44 Colt
The cartridge was developed by Colt's Patent Firearms for use in cartridge revolvers based on the 1860 Army percussion revolver. It was briefly adopted by the United States Army around 1871 and used until 1873 when it was replaced by the more powerful .45 Colt cartridge, which was used in the newly adopted Colt Single Action Army revolver. The .44 Colt was specifically designed for use in the Richards-Mason conversion of Colt's 1860 Army percussion revolver. This conversion process involved boring through the chambers of the obsolete cap and ball revolvers and adding a breech-plate with a gated loading port to enable them to chamber centerfire metallic cartridges. As a result of this process, the chamber had a uniform diameter with no step at the front. This meant that the bullet and brass case shared the same diameter, typically measuring between .451 and .454 inches, with a short "heel" section at the base of the bullet of smaller diameter inserted into the mouth of the case. This construction is similar to that of .22 rimfire ammunition. Modern .44 Colt ammunition closely resembles .44 Special in terms of bullet diameter and case width, with the main differences being the shorter case length and smaller rim diameter.

6mm Arc
.45-70 Govt
The .45-70, also referred to as the .45-70 Government, .45-70 Springfield, and .45-21/10" Sharps, is a .45 caliber rifle cartridge initially designed to hold 70 grains of black powder. It was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873. This cartridge served as a replacement for the stop-gap .50-70 Government cartridge, adopted in 1866, a year after the conclusion of the American Civil War. Collectors commonly know it as the "Trapdoor Springfield."
7mm Weatherby Mag
The 7mm Weatherby Magnum is a potent rifle cartridge from the Weatherby firearms company, initially featured in their Mark V rifles. Developed by Roy Weatherby in the early 1940s, it was among the first cartridges introduced by Weatherby. Derived from the .300 Holland & Holland Magnum case, it is necked down to 7mm (.284) with a distinctive double-radius shoulder. The case design eliminates taper, allowing it to feed from standard-length actions like the .257 Wby Mag and .270 Wby Mag. Although the 7mm Weatherby Magnum gained prominence in the early 1950s with increased availability of Weatherby rifles, the more widely popular 7mm Remington Magnum, introduced in 1962, shares similar ballistics. Despite being introduced 18 years earlier, the 7mm Weatherby Magnum, due to its case design, offers a slight ballistic edge over the 7mm Rem Mag. However, the Remington's availability in more affordable and widespread rifles contributed significantly to its enduring popularity. Weatherby's initial 7mm rifles had 1:12" barrels, too slow for stabilizing heavier bullets. In response to the introduction of the 7mm Rem Mag with a 1:9 1/4" barrel twist, Roy Weatherby modified the twist to 1:10 for enhanced performance.

50 Beowulf
The .50 Beowulf is a 12mm caliber rifle cartridge created by Bill Alexander of Alexander Arms specifically for use in an AR-15 rifle. Featuring a rebated rim designed to match the 6.5mm Grendel round, the case body closely resembles the dimensions of the .500 S&W Magnum revolver cartridge, with a slight increase in length and full taper for seamless automatic feeding. Designed to significantly enhance stopping power at short to medium ranges compared to the standard 5.56×45mm NATO round, the .50 Beowulf finds application in various scenarios, including vehicle checkpoints. Its heavy bullet's flight path is less prone to deflection by auto glass or standard vehicle body panels, making it a notable choice for specific tactical purposes.
