I am loading with IMR-4350.
Other good choices, one downside to the IMR is its long grain and does not dispense real well.
I don't care as I setup to under dispense and trickle on up to the right level
The gun I am loading for (family gun) does not care for factory ammo and is looking much better with the IMR.
It has a good wide range and I like that in a powder as those tend not to be picky (you can hit the sweet spot easily as you just have to land in a fairly wide band with the IMR) . Then see where it sits for velocity and you may just leave it there.
