From looking at my notes I loaded 129sst and 140sst.
I settled on 56.6 which gave me 2950 fps with the 140 sst and the same load with the 129sst produced just over 3000 fps.
The same load gave me 2950 with the 143 eldx, most groups were about 1/2 moa.
At 57 .2 of SP I got ejector swipe and heavy bolt lift, pressure can rise very quickly with this powder so be carefull especially on hot days.
Load development was over a magnetospeed v3

Thanks for that @Doon load data for Superformance is patchy at best which is a shame because it is such a good powder. I haven't got the rifle yet but once I do I'll be mucking around with some Superformance but haven't decided on projectile yet
