The 7mm Winchester Short Magnum cartridge, a rebated rim bottlenecked centerfire short magnum introduced in 2001, is probably the closest ballistic twin of the 7mm Remington Magnum. The 7mm Winchester Short Magnum is considerably shorter and fatter and has a steeper shoulder angle and a shorter neck (6.17 mm) than the 7mm Remington Magnum. This ...
Four of Nosler's Cartridges, .26 Nosler, .28 Nosler, .30 Nosler and .33 Nosler, are based on the same .300 Remington Ultra Magnum [6] parent case. While the .26 Nosler and .28 Nosler share the same cartridge case dimensions, the .30 Nosler has a slightly shorter length to the shoulder dimension than the .26 Nosler and .28 Nosler, [ 7 ] and the ...
However, the published data is provided from a .280 AI tested with a 26" barrel rifle, while the 7mm Rem Mag was tested with a 24" barrel, which suggests that the velocity advantage should increase in favor of the 7mm Remington Magnum if both cartridges were tested from rifles with similar barrel lengths, and especially from reloads.

By way of comparison, the .416 Rigby and .416 Remington Magnum cartridges fire .416 in (10.57 mm) bullets of 400 gr (26 g) at 2,400 feet per second (730 m/s) with a muzzle energy of approximately 5,000 foot-pounds force (6,800 N⋅m). These cartridges exceed the ballistic performance of the .404 Jeffery but at the price of greater recoil and ...

Ackley's loads only managed 4,600 ft/s (1,400 m/s)(Mach 4.2), firing a 50-grain (3.2 g) bullet. Based on a .378 Weatherby Magnum case, the case is impractically over-capacity for the bore diameter, and so the cartridge remains a curiosity. The advent of new slower-burning smokeless powders may have changed the equation.
The 7mm Shooting Times Westerner, sometimes referred to as the 7mm STW, began as a wildcat rifle cartridge developed by Layne Simpson, Field Editor of Shooting Times, in 1979. [3] It is an 8mm Remington Magnum case that has been "necked down" (narrowing the case opening) by 1 mm to accept 7 mm (.284 in) bullets.
