Just to add my .02 - the Savage short action is dandy for the .284 Win. I built one on a long action and then realized I didn't need the long action because all my loads were a hair under 3.00" and you can fit that into a Savage short action. So I sold the rifle, bought a short action LW Storm, and am having another .284 Win barrel made for it.

Most other manufacturers short actions are limited to 2.80" which I wouldn't use for a .284, but with Savage's 3.00" mag box, it's a great fit for the cartridge.
