I was using VV N110 and just using a Lee dipper too. Its the main recommended powder by Melvin and very popular in the Savage too. I did check the dipper against my scale first and i was throwing just a tiny bit less than the conversion card stated. It is by far the smoothest feeling ML barrel ive tried when loading a sabot and the trigger is better than any i have ever owned.
I like it so much i might just have to see if he will still make a 45cal but i want a faster twist than he was offering. He will order a custom twist barrel but ive heard he stopped making 45s.
