The .243 produces a velocity of 3,200 feet (980 m) per second from factory-loaded expanding monolithic copper projectiles weighing 85 grains (5.5 g) fired from a 24-inch (610 mm) barrel. [28] Other variations of commercially loaded .243 ammunition are available with bullet weights ranging from 55 grains (3.6 g) up to 115 grains (6.8 g).
What the 6.5-08 provided over the .243 Winchester, .308 Winchester, and to a lesser degree the 7mm-08 Remington was bullets with excellent ballistic coefficients and sectional densities. Since the 6.5-08 was a wildcat cartridge, variations existed between cartridge chambers depending on the reamer used to cut the chamber.
In December 1955, Guns Magazine writer, H. Jay Erfurth in an article titled Two Varmint-Big Game Rifles discussing the .244 Remington and .243 Winchester wrote "the Winchester bullet of 100 grains is the better one for deer and medium game than the 90-grain Remington pointed soft-point, though the differences seem mostly splitting hairs." He ...
The 6mm-06 can drive a 105 grain .243 caliber projectile in excess of 3200 feet per second (fps), giving the 6mm-06 a ballistic advantage over the non-magnum .243 offerings from Winchester and Remington, particularly at longer ranges.
The 7mm-08 with 139-140 grain loads does well against some 150-grain .308 Win. loads, providing good energy levels. One example is the Remington 7mm-08 140 PSP (1490 fpe at 300 yards) compared with the Remington 308 150 grain PSP (1344 fpe at 300 yards). [14] The 7mm-08 invites a ballistic comparison with the veteran, highly esteemed 7×57mm ...

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.
