Why? Don't need it. Just start with 223 data and work up.
None of the following manuals have an entry for .223 Ackley or .223 AI: Hornady, Speer, Sierra.
The 223 cartridge guide right on this site has a little info on this

Ya,have been doing the experimental thing. Load it up to the top and look for pressure signs. I load lighter bullets in mine. Problem is that I have over 1k rounds through my barrel experimenting. It is fun though. Anyone use Reloader 15 in theirs? Right now my favorite powder for accuracy is 748. I can shoot a compressed powder charge with 55 grain bullets. Only other powders that I have not tried are the Ramshot ones.
I've loaded:
29gr of Ramshot TAC in my 223AI using 50gr Speer HP. 20" 1:12" barrel, PPU brass, Rem 6 1/2 primers. Was around 3200fps.
29.5gr TAC, 40gr VMAX, PPU brass, R 6 1/2 primer was around 3350fps
These are both compressed and max.
For reference using TAC in a .223 Wylde chamber:
24grs of TAC, 68gr BTHP, PPU brass, Win SR, Armalite M15 Comp, 18" 1:8 gets me about 2750fps
Those first to loads are about what I am getting out of my 222. Must be the short barrel you are using.

RL-15 is a little slow for the 223, but I'm sure it would work well. I use RL-15 in my 204 Ruger with 39gr Sierra BK's at over 4,000 fps. Not a compressed load, but the case is completely full to get those speeds. I am planning on trying RL-15 in my 20 TAC which is about the same case capacity as the 223 Ackley.

While Sierra do list seven AI cartridge, alas 223 AI not one of them, as already pointed out. The seven are:
22-250 AI
6mm Rem AI
250 Savage AI
257 Roberts AI
25-06 AI
280 Rem AI
30-06 AI
Interesting that nearly half are quarter bores.

IMR 8208 XBR. Good stuff.

I gave up using the ball powders. To difficult to pick up with my tweezers. Try IMR 8208 XBR.
From your list, the 250 Ackley offers the greatest increase, with the 257 Ackley not far behind.

Not published by Sierra, but as I recall right behind 250 Savage for % capacity increase (of modern, mid-size, mainstream rimless cartridges) would be 6.5mmx55 Swedish.
