History of the .280 Ackley Improved cartridge:

The first version of this cartridge was invented by P.O. Ackley (a famous wildcatter of over 27 different wildcats) by necking down the 30-06 Springfield case to 7mm and fire forming them to a 40 degree shoulder angle and calling it the 7mm-06 Wildcat.

After Remington standardized the 280 Remington, Fred Huntington (another well known wildcatter) tried several should angles to improve it and the 30 degree angle was the most popular.

Then Ackley dropped the fire forming of the 30-06 and changed to the 280 Remington case necked to 7mm with a 40 degree angle for more powder.

Long story short, the Ackley design stood the test of time and is now a standardised SAAMI cartridge and technically no longer a wildcat.
