IMR 7828 shot, real "Well" ( producing GOOD Group's and, Velocities ) in my 7 mm Rem Mag w/ 160 grain class, bullets.
Hogdon and Hornady, should Have, Data with, Min / Max., Loads.
For Me, the best Accuracy was always Found at, around 1/2 to, One Grain Under, Max Powder Charge that, the Rifle would, "Tolerate" !
Good Luck ! Sorry but, I threw Out my Load Data, several years ago when, I got,.. a New Rifle
I shoot federal brass h1000 and 184 bergers at 3000fps in mine. Shoots an easy half moa of if I do my part. Don't worry about using federal brass.
Start around 65gr of h1000 and work up. You'll probably find pressure around 70ish grains
