Varget and 4064 are my powders of choice, but I've had good luck with 380, better with 4350.
I've not had good luck with 748 as loads developed in summer aren't solid in the fall.
Make sure brass is trimmed & necks annealed; that makes a huge difference in velocity.
My preference is CCI primers over Federal too. Lots of variables to play with.
