How about a rifle for all conditions.
It could be stamped:
.280 rem, 7mm express, 7mm-06, .280 whelan
Four in one. Talkin' about getting your monies worth. Huh.
That would end a lot debates on ....... vs ........
Pure genius from a marketing standpoint.

Can't be done -- because while the .280 Remington and 7mm Express are exactly the same case, the 7mm-06 is not. It is based on a .30-06 case, and is enough shorter in the shoulder length that you can't load .280/7mm Express brass in true, genuine 7mm-06 chambers. Assuming that the ".280 Whelen" is based on nothing but a Whelen case necked down to .284 -- you won't be able to chamber .280/7mm Express catridges in it either.
So you have a minimum of two, and perhaps three, chambers and cases for them described...
