I got my 8 twist to shoot the 62s, but it likes them hot. I can’t really list the load here because I’m using HBN, because I have a lot of it and I don’t wish to just throw it away, so my loads are a little different than yours would be. I will say that I have found that TAC and 2230 have worked well for me so far.
I did find some good loads for the Hornady 52 and 55 BTHP bullets from Midsouth. I also found that, in my barrel, the 62 ELD VT does like a squeaky clean barrel. It doesn’t shoot them spectacularly, but it’s minute of coyote quite a ways out there.
