Why would they name these as they did? 6.5-284 Norma? Why not the 6.5 Norma or something else? Why the .338-06 A-square? They didn't call the .270 win the 270-06 or the 280 rem the 7mm-06?

Because it reflects the parent case, in the case of the 6.5x284, the company name in the case of the A Square.

The 270 was named by Winchester. The 280 is not the same as the 7-06 but early guns made in that caliber WERE marked 7-06.

Winchester nearly always either changes a cartridge name to reflect it's their "invention", like they did the 240 Page Super Pooper to 243, and Remington nearly always keeps the old name and tacks there's on behind, like the 22-250, 25-06 and 7mm Rem Mag.

Marketing.

The 6.5-.284 Norma denotes that it is based on the .284 Win. round (popular among U.S. wildcatters) and Norma connotes quality. For all I know, they do call it the 6.5 Norma in Europe.

The .270 Winchester was designed by Winchester, hence the name. There was little reason to give attribution to the parent cartridge.

The .280 Rem. was once known as the 7mm-06 before it was commercialized, and the 7mm Remington Express when Remington first introduced it.
