The American .280 Remington cartridge is probably the closest ballistic twin of the 7×64mm. When compared to the 7×64mm, the .280 Remington has a slightly lower maximum allowed chamber pressure and as an American 7 mm cartridge has a slightly smaller groove diameter. European 7 mm cartridges all have 7.24 mm (0.285 in) grooves Ø diameter. [6]
.280 Remington vs 7x64 Brenneke [ edit ] In Europe the .280 Remington is not popular in bolt-action rifles since it competes directly with the 7×64mm , which is of the almost exact same size as the .280 Remington but has slightly more power, because of having a slightly higher maximum allowed chamber pressure and a slightly higher case capacity.
The .280 Ackley Improved (.280 AI) was the result of the .280 Remington case modification by P.O Ackley, who pushed out the sidewalls at the shoulder to near parallel and steepened the shoulder angle to 40 degrees in order to increase powder capacity, thus along with increasing the allowable pressure, resulted in increasing the bullet initial velocity by approximately 100 fps.

Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
The .284 Winchester was designed to achieve .270 Winchester and .280 Remington performance from the new Winchester Model 100 autoloader and Winchester Model 88 lever-action rifles. The result was a 7 mm cartridge with about the same overall length as the .308 Winchester but with a wider body, that yields a powder capacity about the same as that ...
Internal ballistics (also interior ballistics), a subfield of ballistics, is the study of the propulsion of a projectile. In guns , internal ballistics covers the time from the propellant 's ignition until the projectile exits the gun barrel . [ 1 ]
