.280 Remington brass?

Can I run 30-06 or 270Win cases into my .280 Rem full length resizing die and produce safe, usable brass?

NO, the body length from base to start of shoulder taper is longer on the 280 by about .05.
This is a very critical dimension (the head space) & simple reforming without fire-forming (blowing out) would result in an unsafe condition of very short cases (excessive head-space).
I feel it can be dangerous to re-form any case to something other than the head-stamp & should be avoided if at all possible.
280 Rem brass is readily avalible & the few pennies saved would be meaningless if a family member were to load the wrong cartrige because of the head stamp.

Making false shoulders to provide a new place for headspace is a common practice for those of us who design and build wildcat cartridges. There is nothing dangerous about this process so long as you pay very close attention to every detail in the process. Check and double check everything. Since using a parent cartridge to create a new cartridge still leaves the parent headstamp, you need to exercise great care in keeping these new cases segregated from the other brass with the same headstamp. This isn't rocket science and 10's of thousands of us use this practice on a daily basis. A good pair of calipers will answer any questions about which case is which.
This is an example of creating a false shoulder in order to create the new point of headspace:
It's important to use dimension drawing when trying to determine if some case forming is possible. These are available in some reloading manuals and from several online resources. One of the better resources is Steve's Pages, just remember he provides these resources for free so don't be a hog.
Another good source of dimension drawings is the Norma Powder website.
Best.
