7 mm rem mag Nossler LR 168 reload recipe

[Edsknives]

I have been using recipes on line by Nossler.They recommend mag pro 4000mr and Magnum.I have used Mag pro and 4000mr.I havent found the sweet spot yet.I am wondering what Nossler factory ammo uses for powder? My rifle groups well with that ammo how do I find that powder for 168 7mm rem mag Long Range.
