When I first looked at the 123gr SST, I suspected a BC difference from the 123gr A-MAX, since the SST has more of a tangent ogive. It seems that your results are reflecting a lower BC value for it. I have not done the type of accurate distance shooting with the SST yet, other than 600yds.
One way to check would be to load the same charges and other components, and alternate SST/A-MAX to see if there is a vertical dispersion. My suspicion is that there will be one.
Just using G1 data had me almost dead-on at 1200yds with the 123gr A-MAX, after chronographing it and using morning atmospheric data in the afternoon. I was 14.4 Mils at 1200yds.
I think the 123gr SST is a great hunting and target bullet, and it is nice to see some real world data for it at 1000yds, with BC truing featured software. So what G7 BC is working for you with the 123gr SST again, .224 was it?
