The fact that the .243 Win was originally offered in a 1 in 10 inch rifling twist rate, a rate better able to stabilize heavier, 100- and 105-grain bullets, versus the .244 Remington's 1 in 12 inch twist (hence the 90-grain factory offering) was also a factor in their popularity.
The model 510/516 Striker was produced from 1998 to 2005. It had a stainless finish with a left handed charging handle and right hand ejection. It chambered for .223 Rem, .22-250 Rem, .243 Win, 7mm-08 Rem, .260 Rem, and .308 Win with two or three round magazines. Its total length was 570 mm (22.5 inches) (or 610 mm (1 foot) for the rear grip ...
The standard bullet diameter for 6 mm caliber cartridges is .243 inches (6.2 mm), the same diameter used in the .243 Winchester and 6mm Remington cartridges. To obtain maximum accuracy, bullet weight and form are matched to the rifling twist rate of the barrel. Typically, 68 gr (4.41 g) bullets are used in barrels with twist rates of 1 in 13 ...
Chambered in .250-3000 Savage, .300 Savage, .243 Winchester, .308 Winchester and .358 Winchester. 99E: "E" meaning "Economy". The 99E was the more affordable model that eliminated features like the round counter on the side, and machine-checkered stock, and the stock was made from cheaper birch wood rather than walnut like on other models.
The .244 Remington lagged behind the .243 Winchester in the marketplace of the mid-1950s. Winchester also introduced a similar dual purpose cartridge of the same caliber with greater success in 1955, the .243 Winchester, but with 80 and 100 grain bullet options for its Model 70 with a 1 in 10-inch twist to allow for the slightly heavier bullet.
The 243 Winchester Super Short Magnum or 243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM ( Winchester Short Magnum ) case shortened and necked down to accept a .243in/6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency.

A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]
