If a 5.56×45mm NATO cartridge is loaded into a chamber intended to use .223 Remington, the bullet will be in contact with the rifling and the forcing cone is very tight. This generates a much higher pressure than .223 Remington chambers are designed for. [3] NATO chose a 178-mm (1-in-7) rifling twist rate for the 5.56×45mm NATO chambering.
Thus the optimum rate of twist for this bullet should be approximately 12 inches per turn. The typical twist of .30-06 caliber rifle barrels is 10 inches per turn, accommodating heavier bullets than in this example. A different twist rate often helps explain why some bullets work better in certain rifles when fired under similar conditions.
The .223 WSSM was introduced in 2003 by the Browning Arms Company, Winchester Ammunition, and Winchester Repeating Arms Company. The .223 designation is a reference to the popular .223 Remington. It is currently the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second (1,402 meters per second).

Newton recommended loading 100 grain (6.5 g) bullets at 2,800 ft/s (850 m/s); but Savage Arms reduced bullet weight to obtain a velocity of 3,000 ft/s (910 m/s), making it the first American cartridge capable of that velocity. Achieving that velocity may have been the reason for the choice of the light-for-caliber 87-grain (5.6 g) bullet. [3]
Soon after the release of the .223 Remington as a commercial cartridge, shooters began experimenting with the cartridge in an attempt to improve its performance. [1] Several of these experimenters necked up the .223 Remington to 6mm as the .243 inches (6.17 mm) caliber bullets provided better external ballistic performance over .224 inches (5. ...
In 1899, Savage offered to convert any existing Model 1895 rifle or carbine to Model 1899 configuration for a $5 fee. [7] After changes to the Model 1899 receiver and internals in 1908, Savage would no longer work on 1895's or pre-1909 1899's and would instead offer to sell a new rifle at discounted price.
The Savage Striker was a bolt action pistol produced from 1999 to 2005 by Savage Arms for metallic silhouette shooting and hunting.The pistol was based on the action of the Savage Model 110 and was sold with a composite stock, originally with a center grip, but later also with a rear grip as an alternative.
