308 case: 22-243, 243, 25 super, 260 Remington, 7-08.
30-06 case: 6mm-06, 25-06, 6.5-06, 280, 8mm-06, 338-06, 35 Whelan
270 is the 30-03 case, which was parent to the 30-06.

There are several for the 7mm Mauser (7x57)case
There are even wildcats for the the 30-30 case, 30-40 and the 303 case. Just about anything military has been necked down or up.

As Parker said, if you can think of it, good chance its already been done.
