My STW is a 70 Classic stainless with the factory 26" buggywhip.
Pretty much everything else has been gone through and trued, squared or lapped. Even a Winchester has to have the crown done right after it leaves the factory once in a long while.
+1 (or however many)on the 7828. IIRC it's 81 gr. under a 140 AccuBang for a whisker over 3600 (ask THAT of your 7RM !!) and bugholes at 100 yards.
Next thing I need is 10 or 15 minute bases as I can't get beyond about 675 yards with the turrets on the current setup.
