The 2007 thru 2010 AA load booklets do not list AA-2 or AA-5 in any of their 44 mag loads however the 2000 thru 2005 editions do.
These are max loads so be sure to reduce start loads and work up if you use any of these, especially in a lighter framed gun or even in a S&W. For information only... I don't recommend using as is and although not indicated, these may be specific to the heavy duty Ruger.

CCI-300 7.5" Ruger Redhawk
AA-2
240 gr LSWC - 9.0 @ 1178 to 10.0 @1280 fps oal 1.560"
180 JHP Hornady 10.0@ 1328 to 11.1 @ 1444 fps 1.56"
200 JHP Nosler 9.9 @ 1235 to 11.0 @ 1342 fps 1.595"
240 JHP IMI 10.0 @ 1250 fps 1.56"
240 Rainier FP 9.3 @ 1161 to 10.3 @ 1262

Be aware that many of their past loads have been full pressure, to say the least and may even be over pressure by today's SAAMI standards. I would give AA a call before using these just to double check.
Like many have indicated, AA-2 is very fast for the case capacity and there are better choices available.

I noticed you are looking for 800 fps.... under 44 Spl they do show a 245 LRN with 4.2 @ 753 to 4.7 Max of AA-2 clocking 819 fps at 1.6"oal (which is a Mag length- so why did they list this under the Spl heading... [probably] a typo and should be 1.48" or thereabouts.)
