I’m loading this same set up for one of my rifles, the other one is H1000 and the 200 grain accubond. Just because one likes lighter bullets and the other likes a little heavier.All of the above are solid recommendations. You could add a nosler partition/accubond 180 and H4831.
Rl22,26,33 all work really well. A little known powder Winchester WXR and RAMSHOT Magnum also work very wellI shot H-1000 forever and changed over to N-570.. It dropped my ES and SD and 570 shoots one hole now.. It does burn barrel more but, for a hunting gun the accuracy speaks for itself. H-1000 is a great powder but I just couldn't get the same numbers. 215 Berger and Fed 215 primer.
Don’t forget the newer rl23 and especially the old school rl25. With an old 300 of mine I used to have a load with the hornady 220 round nose (not a 1000 steel round, but a beast inside 300 yards, that blunt bullet just plain SMACKED) that hovered right around 2800 feet per second.
