But then again, if you use 30-'06 cases, you won't need to trim them for a long time, maybe never.

No you can NOT use .270 cases for .280. Look at your reloading manuals or cartridge dimension books fellas. The problem starts with the rim diameter of the .270 which is .532". The .280 rim diameter is ..473" which is the same as 30-06.

We're talking about .270 Winchester.
You're looking at .270 Weatherby or .270 WSM. (Neither of which actually has a .532" rim diameter in any drawing that I have, but both are close.)

Those .270s are different beasts, entirely.
.270 Weatherby is based on .300 H&H.
.270 WSM is based on .300 WSM (which is, itself, based on a modified .404 Jeffery).
