I'm still fire-forming the AI part, but we have enough brass to start loads. 
I want to keep them around 2700, or 2800 fps Similar to the factory 7x57 in a 140-ish bullet.
It's for a small framed 14-year-old girl. She has been shooting for 8 years and is very good. But does not enjoy heavy recoil, is not afraid of it but does not like it. 
She is shooting a Ruger American re-barreled with a Shaw barrel 1x7 twist, 22".
This is the first try. 
She is shooting off a bench with sandbags at 100 yards.

LRX 145 gr best of 3 loads.
The recoil with Big Game Powder has noticeably more recoil.

ttsx 140 gr best of 3 loads.
Check out the fire-forming target 20 shots in an inch and a half.
