.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. Although loaded to higher pressures, the ballistics of this cartridge are basically similar to the 6.5×55mm when bullet weights do not exceed 140 grains. When loaded with heavier bullets, the 6.5×55mm is capable of greater velocity. Due to its shorter overall length the .260 Remington can be chambered in a shorter length action than the 6.5×55mm.

6.5×55mm The 6.5×55mm (designated as the 6.5×55 Swedish by the SAAMI and 6,5 × 55 SE by the C.I.P.) is a first-generation smokeless powder rimless bottlenecked rifle cartridge. Other, less common names are 6.5×55mm Swedish Mauser, 6.5×55mm Mauser and 6.5×55mm Krag. It was developed in 1891 for use in the new service rifles then under consideration by the United Kingdoms of Sweden and Norway. The two nations had independent armies and consequently the normal procedure at the time was for their respective governments to use the same ammunition and then purchase small arms of their choice. Norway adopted the Krag–Jørgensen rifle, while Sweden adopted a Mauser rifle design.

Winchester Magnum Winchester Magnum refers to a "family" of cartridges developed by the Winchester Repeating Arms Company, one of the oldest firearms manufacturers in the United States, in the late 1950s and early 1960s, all based on the same basic cartridge case. The basic case was a "short" magnum, meaning it would work through a standard (i.e.; .30-06) length rifle action rather than requiring the longer, magnum (i.e. .375 Holland & Holland) actions.

.340 Weatherby Magnum The .340 Weatherby Magnum rifle cartridge was introduced in 1963 by creator Roy Weatherby in response to the .338 Winchester Magnum. The .340 Weatherby Magnum uses the same .338 in. diameter bullets as the .338 Winchester Magnum but it does so at greater velocity than its Winchester competition. Reloaders may have trouble matching the published Weatherby velocities as Weatherby factory ammunition is loaded to maximum specifications. Weatherby no longer loads the 250gr. round-nose cartridge pictured but continues to load the 250 gr. Spire Point and 250 gr. Nosler Partition. Weatherby has also expanded their factory loads including Nosler Ballistic-tip and Barnes TSX bullets complementing the powerful cartridge. Currently A-square is the only other factory ammunition producer of the .340 Weatherby Magnum which has led to limited popularity of the caliber. In field tests the .340 clearly out performs the 300 Ultra mag, .338 win mag. and even rivals the larger .375 H&H, providing a much flatter shooting and harder hitting performance.

6mm Remington The 6mm Remington rifle cartridge, originally introduced in 1955 by Remington Arms Company as the .244 Remington, is based on a necked down .257 Roberts cartridge using a .24/6mm bullet. Known for a combination of high velocity, long range, and accuracy, it is suitable as a dual use hunting cartridge for both varmints and medium-sized big game. When used in the less common earlier slow twist barrels, it offers exceptional range for varmint applications. While not as commercially popular today as the .243 Winchester, the 6mm Remington enjoys a slightly ballistic advantage and continues to be popular with handloaders and custom rifle builders.

.300 Whisper The .300 Whisper is a CIP standard cartridge in the Whisper family, a group of cartridges developed in the early 1990s by J.D. Jones of SSK Industries. It was developed as a multi-purpose cartridge, capable of utilizing relatively lightweight bullets at supersonic velocities as well as heavier bullets (200–250 grains) at subsonic velocities.

.22 Winchester Centerfire .22 Winchester Centerfire (.22 WCF) is a small centerfire cartridge introduced in 1885 for use in the Winchester Model 1885 single-shot rifle. Factory manufacture of ammunition was discontinued in 1936. The .22 WCF was loaded with a 45 grain bullet with a muzzle velocity of about 1550 feet per second, similar to the performance of the .22 Winchester Rimfire (.22 WRF) designed in 1890.

8mm Remington Magnum The 8mm Remington Magnum belted rifle cartridge was introduced by Remington Arms Company in 1978 as a new chambering for the model 700 BDL rifle. The 8mm Remington Magnum's parent case is the .375 H&H Magnum. It is a very long and powerful cartridge that cannot be used in standard length actions, such as those that accommodate the .30-06 Springfield.

8×60mm S The 8×60mm S (the S means it is intended for 8.2 mm (.323 in) groove diameter bullets) is an uncommon rimless bottlenecked centerfire cartridge of German origin, dating back to the interbellum period between World War I and World War II. As is customary in European cartridges the 8 denotes the 8 mm bullet caliber and the 60 denotes the 60 mm (2.362 in) case length. The 8×60mm S can, due to its 83.6 mm (3.291 in) overall length, easily be chambered in standard sized Mauser 98 bolt action rifles.

.222 Rimmed The .222 Rimmed is a centrefire rifle cartridge, originating in Australia in the 1960s as a cartridge for single shot rifles, particularly the Martini Cadet action. Performance is similar to the .222 Remington on which it is based however loads should be reduced as the walls of the brass cases are generally thicker.

Musket A musket is a muzzle-loaded, smoothbore long gun that appeared in early 16th century Europe, at first as a heavier variant of the arquebus capable of penetrating heavy armor. By the mid-16th century, this type of musket went out of use as heavy armor declined, but as the matchlock became standard, the term "musket" continued as the name given for any long gun with a flintlock, and then its successors, all the way through the mid 1800s. This style of musket was retired in the 19th century when rifled muskets (technically rifles, but still referred to as muskets) became common as a result of cartridged breech-loading firearms introduced by Casimir Lefaucheux in 1835, the invention of the Minié ball by Claude-Étienne Minié in 1849, and the first reliable repeating rifle produced by Volcanic Repeating Arms in 1854. By the time repeating rifles became common, they were known as simply "rifles", ending the era of the musket.

.40-60 Winchester The .40-60 Winchester is a centerfire rifle cartridge intended for 19th-century big-game hunting. Nomenclature of the era indicated the .40-60 cartridge contained a 0.40 in diameter bullet with 60 gr of gunpowder. Winchester Repeating Arms Company necked down the .45-60 Winchester cartridge to hold a bullet with improved ballistics for the Winchester Model 1876 rifle. The lever-action Model 1876's advantage of faster loading for subsequent shots was eclipsed two years later by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges with heavier bullets. The .40-60 and similarly short cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of cartridges designed for stronger rifles. Winchester production of .40-60 cartridges ended during the great depression.

7mm-08 Remington The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length. Of cartridges based upon the .308, it is the second most popular behind only the .243 Winchester. However, the .308 is more popular than both. In 1980, the Remington Arms company popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles.
