I recently started casting NOE's .225-55-rnfp to use in my 223 T/C and AR.

I have one load that is extremely accurate with 6gr of Unique, but need some decent load data using AA2520 powder. Any load data available that has been tested?

The above link will take you to the web page for Accurate arms powders. Lots of loads for 223 in the powder you asked for. None of the listed loads are for cast as far as I can tell. However, you can use a start load a 10% under the listed start for jacketed boolits and go from there.
Your mileage may vary. Some powders are unsuitable for reduced loads in rifles.

I use 20 gr. of AA2520 in my 1:9 twist AR with the 55 gr. RCBS boolit out of WW. Cycles the action and very light recoil. Tried faster powders but the pressure signs were too high and would fail to eject or feed.
