Well, since this is strictly for entertainment purposes...a candidate for "efficient and versatile short action" would be the .325WSM. I've been playing with one this year, not because I had a huge desire for the cartridge but rather because I got a great deal on a BLR takedown model in that chambering and I wanted to play with that gun. Perhaps not the best choice for the crowd that takes those 500-yard-and-longer shots (you know, because no other shot was presented and they had
no choice), but a good mid-level performer, big enough for most targets, small enough for most shooters, decent bullet weight selection and velocities, and easy to shoot. The gun itself shoots as well as most bolt actions, carries beautifully, and packs away easily and compactly for travel. Probably not what I would grab as my one-and-only...okay, definitely not

...but no worse an option that many others touted here. For a gun/cartridge combo that can be squirreled away in your vehicle while away from home at a jobsite, and then used with great effect during a hunting trip that presents itself while you are on your travels, without having an arm and a leg invested in it in case something goes poorly...it has a lot going for it.
Speaking hypothetically, of course.
