JARACAL

The 6mm Remington was introduced by Remington Arms Company in 1955 as the .244 Remington. It is based on necking down the .257 Roberts. Originally intended as a Varmint and predator cartridge, the .244 was never factory loaded with bullets over 90 grains. Rifles marked .244 Remington have a 1 in 12-inch (300 mm) twist that may not stabilize the heavier 100 and 105 grain bullets. Originally Remington offered factory ammunition with 75 grain bullets for varmints and 90 grain for deer. In 1963 Remington renamed the cartridge, calling it the 6mm Remington. Rifles marked 6mm Remington have a 1 in 9-inch (230 mm) twist and can stabilize all commercially available 6 mm bullets.[1]

The 6mm Remington has a slight ballistic advantage over the much more popular .243 Winchester due to a slightly larger case capacity. The longer case neck of the 6mm Remington is considered desirable by handloaders. Noted Alabama deer hunter and marksman Creath Davis is a proponent of this caliber.

Its renaming from ".244 Remington" to "6mm Remington" is interesting. It was discovered soon after its release as .244 Remington that in the Remington Model 721 rifles the rate of twist used in the barrels would not stabilize heavier bullets weighing more than 90 grains. This led to a poor reputation for the cartridge as being "inaccurate." Remington soon increased the rate of twist in its Model 721 rifles, but the marketability damage was already done as far as the cartridge was concerned. Therefore the name was changed to 6 mm Remington. The .244 Remington and the 6 mm Remington are identical - only the name changed.

This cartridge was first introduced in 1955 for Winchester's Model 70 bolt-action and Model 88 lever-action sporting rifles and quickly gained popularity among sportsmen worldwide.[1]  Just about every major manufacturer offers rifles chambered in .243.

Since the enactment of the 1963 Deer Act in the United Kingdom, which stipulated a minimum bullet diameter of .240 in., together with minimum levels of muzzle velocity and bullet energy, the .243 is now perceived as the entry-level caliber for legal deer-stalking. Consequently, it is now the most widely used deer round in the United Kingdom.[citation needed] Firearms that would normally be chambered in .308 Winchester/7.62x51mm NATO are sometimes available in .243 in. countries ? such as France and Spain ? whose regulations restrict or forbid private ownership of so-called military calibers.

In a non-sporting context, bolt-action rifles chambered for the .243 were utilized by the Los Angeles Police Department's Special Weapons And Tactics (SWAT) unit during its early years.[citation needed]

P. O. Ackley created an improved version of this cartridge called the .243 Winchester Improved (Ackley).[2] Like other improved cartridges, this created a steeper shoulder and blew the sides out, plus slightly lengthens the case, giving about 10% more powder capacity, and some small improvement in velocity. Both versions of the .243 cartridge are good for hunting deer.
