The .25-06 Remington was a wildcat cartridge for nearly half a century before being standardized by Remington in 1969.
Its design was based on the .30-06 Springfield cartridge necked-down (case opening made narrower) to .257 caliber keeping a similar cartridge length of its parent case, thus being chambered in standard-length actions. Nominal bullet diameter is 0.257 in, and bullet weights range from 75 to 120 grains (4.9 to 7.8 g).
Charles Newton necked down the .30-06 Springfield cartridge in 1912 to accept a 117-grain .25-35 Winchester bullet, [3] but the resulting .256 Newton cartridge did not catch on. Newton's early modification encouraged commercial release of a shortened case (from 63 to 49 mm) as the .250-3000 Savage in 1915. [4] Frankford Arsenal developed an experimental .25-06 during World War I; and distribution of surplus United States military equipment through the Civilian Marksmanship Program following the war encouraged independent gunsmiths to experiment with the cartridge. [3] A. O. Niedner of Dowagiac, Michigan, introduced rifles for the .25 Niedner in 1920. [5] Niedner Arms Corporation retained the 17° 30′ .30-06 shoulder chambering .25 caliber barrels rifled with one twist in 12 inches (300 mm). [6] Similar cartridges were identified as the .25 Hi-Power, .25 Whelen (analogous to .35 Whelen), or .25-100-3000 (to indicate the ability to achieve 3,000 feet-per-second with a 100-grain bullet rather than the 87-grain bullet used in the .250-3000 Savage). Greater case capacity offered minimal velocity improvement over the .250-3000 Savage case with contemporary smokeless powders. [7] Availability of DuPont's Improved Military Rifle (IMR) powders encouraged commercial release of the .257 Roberts using the 57 mm Mauser case in 1934. [8] Release of IMR 4350 in 1940 and availability of surplus 4831 powder salvaged from Oerlikon 20 mm cannon cartridges after World War II greatly improved performance of the full-length .25-06 case. [9]
Most .25-caliber bullets have high ballistic coefficients without being heavy, which, combined with the large case capacity of its parent .30-06 case, allows relatively high muzzle velocities without heavy recoil. The combination of high ballistic coefficients with high muzzle velocities gives the .25-06 a very flat trajectory as well as retaining kinetic energy down-range.
The cartridge is capable of propelling a 117 grain (7.6 g) bullet at up to 3,200 feet per second (980 m/s) and energy levels up to 2,500 ft⋅lbf (3,400 J). Bullets lighter than 75 grains are available in .257 caliber but were designed for the smaller .25-20 Winchester and .25-35 Winchester cartridges and are too lightly constructed for the high velocities of the .25-06.
The cartridge has less felt recoil than a .30-06 in a similar-weight rifle, due to the lighter-weight bullets used. Shooters who are recoil sensitive will find the recoil from the .25-06 easier on the shoulder, contributing to good shot placement. This cartridge is not quite as powerful as the .257 Weatherby Magnum, usually running 200–300 ft/s (61–91 m/s) slower with a given bullet weight, but almost 200 ft/s faster than the .257 Roberts at its hottest loads (i.e. .257 Roberts +P). [10]
The .25-06 is generally considered to be a good round for medium-sized game such as deer and antelope because of its combination of substantial kinetic energy and moderate recoil. The addition of a flat trajectory makes it particularly popular in open terrains such as plains and mountains, where longer-range shots on game are not seldom, since its flat trajectory forgives range-estimation errors up to 300 yards if sighted to its maximum point blank range.
Bullets of different weights and construction make the .25-06 Remington a fine alternative for hunting species ranging from prairie dogs and coyotes to mid-sized deer and sheep. Although capable of taking heavier game such as elk, many hunters prefer a larger caliber and a heavier bullet for larger species.
Bullets range from lightly constructed 75-grain bullets with muzzle velocities in the 3,700 ft/s (1,130 m/s) range to more robust 120-grain bullets with muzzle velocities in the 3,000 ft/s (915 m/s) range. Most manufacturers of bolt-action or single-shot rifles offer the .25-06 as a standard chambering and factory loaded ammunition is available from Remington, Winchester, Federal Cartridge and most other major manufacturers.

The .308 Winchester is a smokeless powder rimless bottlenecked rifle cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar, but not identical, to the 7.62×51mm NATO cartridge.
The .460 Weatherby Magnum is a belted, bottlenecked rifle cartridge, developed by Roy Weatherby in 1957. The cartridge is based on the .378 Weatherby Magnum necked up to accept the .458-inch (11.6 mm) bullet. The original .378 Weatherby Magnum parent case was inspired by the .416 Rigby. The .460 Weatherby Magnum was designed as an African dangerous game rifle cartridge for the hunting of heavy, thick skinned dangerous game.
The .243 Winchester (6×52mm) 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.
The .270 Winchester is a rifle cartridge developed by Winchester Repeating Arms Company in 1923, and it was unveiled in 1925 as a chambering for their bolt-action Model 54 to become arguably the flattest shooting cartridge of its day, only competing with the .300 Holland & Holland Magnum, also introduced in the same year.
The .375 Remington Ultra Magnum, also known as the .375 RUM is a .375 rifle cartridge introduced by Remington Arms in 2000. The cartridge is intended for large and dangerous game.
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, along with a limited-run series within their Model 7600 pump-action rifles during the early 2000s.
The .30-30 Winchester / 7.8x51mmR cartridge was first marketed for the Winchester Model 1894 lever-action rifle in 1895. The .30-30, as it is most commonly known, along with the .25-35 Winchester, was offered that year as the United States' first small-bore sporting rifle cartridges designed for smokeless powder. Since its introduction, it has been utilized alongside the development of flatter shooting cartridges, most prominently those derived from designs subsidized by interest in military expenditures. The .30-30 has remained in widespread use almost entirely because of reliable effectiveness in civilian applications, and has put food on the table for millions of people in hunting situations.
The .300 Winchester Magnum is a belted, bottlenecked magnum rifle cartridge that was introduced by the Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet.
The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms. It was designed to fill the gap left when the older .45-70 cartridge was no available in new lever-action rifles; at the time it was the largest lever-action cartridge available. The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle. Currently, Marlin, now owned by Ruger Firearms, does not offer the .444 chambering in any of their rifles. It remains to be seen if they will bring the chambering back into production.
The .338 Winchester Magnum is a .338 in (8.6 mm) caliber, belted, rimless, bottlenecked cartridge introduced in 1958 by Winchester Repeating Arms. It is based on the blown-out, shortened .375 H&H Magnum. The .338 in (8.6 mm) is the caliber at which medium-bore cartridges are considered to begin. The .338 Winchester Magnum is the first choice among professional brown bear guides in Alaska to back up clients where a powerful stopping caliber is required on charging bears. It is also the most popular medium-bore cartridge in North America and has the most widely available choice in rifles among medium bore rifles. The action length is the same as a .30-06, and most major rifle manufacturers in the United States chamber rifles for the cartridge including the semi-automatic Browning BAR Mk II Safari, making it a very powerful combination against charging dangerous game. The cartridge was intended for larger North American big-game species and has found use as for the hunting of thin-skinned African plains-game species.
The 7mm Remington Magnum rifle cartridge was introduced as a commercially available round in 1962, along with the new Remington Model 700 bolt-action rifle. It is a member of the belted magnum family that is directly derived from the venerable .375 H&H Magnum. The original purpose of the belted magnum concept taken from the .300 H&H Magnum and .375 H&H Magnum, was to provide precise headspace control, since the sloping shoulders, while easing cartridge extraction, were unsuitable for this purpose. Improved cartridge extraction reliability is desirable while hunting dangerous game, in particular when a fast follow-up shot is required. The 7mm Remington Magnum is based on the commercial .264 Winchester Magnum, .338 Winchester Magnum, and .458 Winchester Magnum, which were based on the same belted .300 H&H Magnum and .375 H&H Magnum cases, trimmed to nearly the same length as the .270 Weatherby 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.
The .257 Roberts, also known as .257 Bob, is a medium-powered .25 caliber rifle cartridge. It has been described as the best compromise between the low recoil and flat trajectory of smaller calibers such as the 5 mm and 6 mm, and has more energy, but is harder recoiling, similar to larger hunting calibers, such as the 7 mm and 7.62 mm.
The .358 Winchester / 9.1x51mm is a .35 caliber rifle cartridge based on a necked up .308 Winchester created by Winchester in 1955. The cartridge is also known in Europe as the 9.1x51mm.
The .250-3000 Savage is a rifle cartridge created by Charles Newton in 1915. It was designed to be used in the Savage Model 99 hammerless lever action rifle. The name comes from its original manufacturer, Savage Arms, and the fact that the original load achieved a 3,000 ft/s (910 m/s) velocity with an 87 grain bullet.
The 7-30 Waters cartridge was originally a wildcat cartridge developed by author Ken Waters in 1976 to give better performance to lever-action rifle shooters than the parent .30-30 Winchester cartridge, by providing a higher velocity and flatter trajectory with a smaller, lighter bullet. By 1984, Winchester introduced a Model 94 rifle chambered for the 7-30 Waters, establishing it as a commercial cartridge. In 1986, Thompson/Center began chambering 10-inch, 14-inch, and 20-inch Contender barrels for the cartridge.
The 6.5mm Creedmoor (6.5×48mm), designated 6.5 Creedmoor by SAAMI, 6,5 Creedmoor by the C.I.P. or 6.5 CM or 6.5 CRDMR for short, is a centerfire rifle cartridge introduced by Hornady in 2007. It was developed by Hornady senior ballistics scientist Dave Emary in partnership with Dennis DeMille, the vice-president of product development at Creedmoor Sports, hence the name. The cartridge is a necked-down modification of the .30 Thompson Center.
The .338 Marlin Express is a cartridge developed by Marlin Firearms and Hornady. It is based on the .376 Steyr with a goal to duplicate the venerable .30-06 Springfield's performance in a cartridge compatible with lever-action firearms. The cartridge uses a slightly shorter, rimmed case to function in lever-action rifles with tubular magazines. As introduced in Hornady's LEVERevolution line of cartridges, it follows the design logic of the .308 Marlin Express which preceded it. The .338MX fires heavier .338 caliber bullets than the .308 Marlin Express at roughly the same velocity. It is chambered in Marlin's Model 338MX and 338MXLR rifles using the Marlin Model 336 action.
The .277 Wolverine (6.8x39mm) is a wildcat cartridge. It is a multi-purpose mid-power cartridge with increased ballistic performance over the AR-15's traditional .223 Remington cartridge. The use of a modified 5.56 case means that at minimum, only a new barrel is needed to convert any 5.56-based firearm to .277 Wolverine.
