What can you get?
The most accurate load I ever fired in my pre-64 was 58gr of H4831 and those Hornadys. Stopped right there as shots here are close, and the extra speed wasn’t needed.
Check the Hodgdon manual. Lots of choices will get you 3000 or better, including StaBall 6.5, the new kid. Make a list of possibles and start looking. Since you are starting fresh, you might consider something you can use elsewhere if it doesn’t work out in the .270, but I’d still lean towards the H4831 if available. According to several people I’ve talked with, the RL22 is tough to find. I gave my unopened jug to a friend.
