7mm short action chamberings?

7mm in short action with standard bolt up to 160 class....7mm-08 is hard to beat without much fuss.
284 Win is the cats a** in a long action but would be only marginally better in the short action due to mag length restrictions.

@Roughrice nailed it, the only others that might be added is the 7mm SAW and the 708 AI, all four are in the same neighborhood.

Well, what are the goals to help guide some suggestions...
I'd look at what you can actually get for components then decide. What bullets can you buy if reloading. What factory ammo can you buy three varieties of right now to see what your rifle likes to eat??
7mm-08, 7SAW, .284 and 7SAUM...

Yeah, If you throw in the magnum bolt... whole new set of options!
Don't know If you already have the standard bolt and receiver but, if so, 7mm-08 is definitely the easy button with factory ammo available in a pinch.

So I have the action which is a 243 right now and leaning towards not having to buy a magnum bolt since I have a 7wsm already. Goals for this project are basically putting together an all around deer rifle. Quick deer drive type shots as well as get down and send one when the situation warrants it. I already have 7-08 brass so there is that part of the equation but to me that is not the deciding factor. Yet. 
.
One question I haven't found a clear cut answer to yet is the real world velocities from the 708 vs 708 ai in longer barrels.

Quick deer drive and longer barrel don't mix in my mind. Hands down the 7mm-08 meets all your metrics.

Lots of, StaBall 6.5 Powder ( Hogdon Data, Work up, CAREFULLY ) and, 150 - 162 grain, Eld-X's / SST's or, 168 Berger, Classic's / H-VLD's will Make,..
the 24 inch, 7-08,.. a whole, nother,.. "Animal" !
NO need to, do the 7-08 AI,.. IF, using,.. StaBall, as my son was pushing 168 Bergers, 2,765 FPS with, IT from, a 22 inch Barrel !
IF you can find, a Magnum Bolt Face,.. go,.. 7 SAUM

I agree with you some what. Barrel length is not set in stone just curious what a guy can get out of those in lo ger tubes

Powder and bullet choices make barrel length much less of a concern or easy to overcome...

My vote is 7mm-08AI.
But having one, i can pretty much attest, your not going to be gaining a whole lot by AI ing the 7mm-08.
With 140gr pills out of a 22" barrel, H414, H4350 and Alliant PP2000MR got me 2,832fps.
Speed demon for me was RL17 at 2,916fps.
But most stable was PP2000MR at ES-6, SD-2.

was there less case stretch with the ai? Or possible accuracy gains?

Accuracy gains, no.
As for case stretch.
I trim every reload with a Lee case gauge trimmer.
After about 2 reloads after the initial fireforming, it started taking some off.
And would each time i reloaded.
But not as much as a standard cartridge.

How far do you want to kill stuff and practice?
If it's 600 plus, I'd pick the bullet thats best for that, so 180 ELDs or Berger. Then I'd do a 7/08 AI throated correctly. Ackley mainly to minimize any brass trimming and a bump in velocity doesn't suck. But straight 7-08 is good to go also.
Of shorter ranges, take your pick. I'd base whatever I did on top quality brass choices.
