The 223 Remington is a rifle cartridge, originally developed in 1957 as a commercial hunting bullet for varmint hunting. The first rifle chambered for it came out in 1963. It has continued to be a popular civilian small game hunting cartridge. Though it finds occasional use on medium game, this is not recommended and is illegal in at least ten U.S. states and the United Kingdom, where the .243 Winchester or similar cartridges are the smallest bore cartridges that are legal for hunting deer.

The .22 Hornet or 5.6×35mmR is a varminting, small-game hunting, survival and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than the rimfire .22 WMR and the .17 HMR, achieving higher velocity with a bullet twice the weight of the .17 HMR bullet. The Hornet also differs very significantly from these in that being a centerfire cartridge makes it reloadable, and thus much more versatile. It was the smallest commercially available .22 caliber centerfire cartridge until the introduction of the FN 5.7×28mm.
The .221 Remington Fireball, often simply referred to as .221 Fireball, is a centerfire cartridge created by Remington Arms Company in 1963 as a special round for use in their experimental single-shot bolt-action pistol, the XP-100.

The .243 Winchester (6.2×52mm) is a popular sporting rifle cartridge. Developed as a versatile short action cartridge to hunt both medium game and small game alike, it "took whitetail hunting by storm" when introduced in 1955, and remains one of the most popular whitetail deer cartridges. It is also commonly used for harvesting blacktail deer, pronghorns and mule deer with heavier rounds, and is equally suited to varmint hunting with lighter rounds. The .243 is based on a necked down .308 Winchester, introduced only three years earlier. Expanding monolithic copper bullets of approximately 80 to 85 grains or traditional lead rounds of 90 to 105 grains with controlled expansion designs are best suited for hunting medium game, while lighter rounds are intended for varmints.
Thompson/Center Arms was an American firearms company based in Springfield, Massachusetts. The company was best known for its line of interchangeable-barrel, single-shot pistols and rifles.

The .30-30 Winchester/.30 Winchester Center Fire cartridge was first marketed in 1895 for the Winchester Model 1894 lever-action rifle. The .30-30 (thirty-thirty), as it is most commonly known, and the .25-35 were offered that year as the USA's first small-bore sporting rifle cartridges designed for smokeless powder. Sixty years after its introduction, in 1955, it was surpassed by the smaller bore .243 Winchester cartridge with more powerful and accurate ballistics yet similar recoil, but the .30-.30 Winchester remains in widespread use even today.

The .257 Roberts, also known as .257 Bob, is a medium-powered .25 caliber cartridge. It has been described as the best compromise between the low recoil and flat trajectory of smaller calibers such as the 5 mm (.22") and 6 mm, and the higher energy but harder recoil of larger popular hunting calibers, such as the 7 mm family and the popular .30-06.
Parker Otto Ackley was an American gunsmith, barrel maker, author, columnist, and wildcat cartridge developer. The Ackley Improved family of wildcat cartridges are designed to be easily made by rechambering existing firearms, and fireforming the ammunition to decrease body taper and increase shoulder angle, resulting in a higher case capacity. Ackley improved not only standard cartridges, but also other popular wildcats, and was the first to create a .17 caliber (4.5 mm) centerfire cartridge.
