Hornady 25 cal 110 gr Interbond anybody??

OK Thanks. That's a new one for me.
There is no load data so you have to extrapolate from other cartridges like the Roberts, that data shows some slow powders like 414, R17, H4350, Hunter . ect. With 80ttsx . so Superformance is slower so one would have to guess at additional grains. The advantage of Superformance is a substantial velocity gain over anything else. I do understand some reloaders are not wanting to guess at a proper powder charge. There is some risk associated.
 
I am shooting a 25x47L. 28" 8 twist. Different case but close. Maybe this will help you find a starting point.

H4350.....115 Berger....about 3000fps @ 41.9 gr.
Went up to 43.0 grains before seeing pressure. 3100 fps

RE-17.....115 Berger.....about 3000fps @39.5 gr
Went up to 41.5 gr before seeing pressure. 3200 fps

RE-16.....115 Berger....about 3000 fps @ 40.3 gr
shot up to 42.0 gr before seeing pressure. 3180 fps
